fix(channels): share chat-to-thread bindings through the database (#6558)
* fix(channels): share chat-to-thread bindings through the database

ChannelManager kept its IM chat-to-thread bindings
(channel_name:chat_id[:topic_id] -> thread_id) in a per-process JSON file,
channels/store.json, loaded once and rewritten whole on every change. With
several Gateway processes a binding created on one replica was invisible to
the others (the next message for the same chat opened a second thread) and
concurrent writers clobbered each other's file.

- New channel_thread_bindings table (migration 0036_channel_thread_bindings)
  and harness package deerflow.persistence.channel_thread_bindings: key PK
  (the legacy composite string), channel_name, chat_id, nullable topic_id,
  thread_id, user_id, epoch created_at/updated_at; index (channel_name,
  chat_id). Dialect upsert keeps created_at; prefix remove and batched
  ON CONFLICT DO NOTHING import.
- app.channels.store.ChannelStore is an async protocol: SqlChannelStore for
  sqlite/postgres, JsonChannelStore (file I/O via asyncio.to_thread) for
  database.backend: memory. resolve_channel_store picks at ChannelService
  construction; ChannelService.start() imports an existing store.json once
  into an empty table and renames it store.json.migrated (a concurrently
  importing peer neither duplicates nor clobbers; a populated table leaves
  the file alone).
- Callers updated: manager, connection_identity.lookup_thread_id, Feishu
  (send() awaits the mapping writer; the synchronous lark callback bridges
  its two store calls to the Gateway loop with a bounded wait), Discord
  (channels_dir).
- Head pins in the 0027_0028/0029/0032/0034/0035 migration tests point at
  the new head; docs (channels and migrations AGENTS.md, CONFIGURATION.md,
  README) and CHANGELOG updated.

* docs(changelog): link the channel thread bindings entry to #6558

* fix(channels): reject only the Gateway loop in the Feishu store bridge

lark-oapi 1.5.5 invokes the message callback synchronously from its async
frame handler, on the private event loop that FeishuChannel._run_ws starts
for the SDK thread. The bridge's guard treated any running loop as unsafe,
so every real inbound message skipped the stored-topic lookup and the
pending-mapping restore: a reply whose parent card was mapped but whose
root was not fell back to the unknown root, and could consume an
unrelated pending clarification.

Only a wait issued from the Gateway loop itself (the loop that executes
the submitted coroutine) is refused now; the SDK's own loop may block for
the bounded wait, as that thread blocked on the JSON rewrite before.
Tests drive _on_message from a worker thread running its own loop, the
production shape, for both the lookup and the write path, and pin the
Gateway-loop refusal.

* fix(channels): defer unresolved Feishu lookups and harden the store.json import

Review follow-ups on the chat-to-thread binding store (#6558):

- Import: a legacy entry whose key, channel_name, chat_id, topic_id,
  thread_id or user_id exceeds its column width is skipped and counted
  with the malformed ones instead of failing the whole batch on
  PostgreSQL (SQLite silently accepted the same row, so the backends
  diverged on one file). The corrupt-file warning now says what each
  caller does: the JSON store starts fresh, the import is skipped and
  the file kept.
- Feishu bridge: store calls run on the Gateway loop under a 3s
  asyncio.wait_for (the SDK loop also services ws keepalives; the old
  10s bound could stall it per message), and the lark-thread wait is
  that budget plus 1s. A deadline or store error is StoreLookupUnresolved,
  never a miss: _on_message no longer routes such a reply onto its
  unknown root (which created a second thread and later overwrote the
  parent alias). The message joins a per-chat FIFO drained on the
  Gateway loop with backoff for up to 30s, then is dropped with a
  warning. _on_message is split into parse / resolve / dispatch so the
  deferred path dispatches the same way; later messages for the chat
  queue behind the deferred one.

* fix(tests): expect follow_redirects in the Jina client kwargs after #5808

#5808 made JinaClient pass follow_redirects=True to httpx.AsyncClient and
updated test_jina_client.py, but test_jina_response_limit.py and
test_jina_retry_after.py still pin the exact client kwargs to proxy and
trust_env, so every backend-unit-tests shard that lands on them fails on
main (the backend unit-test workflow only runs on pull requests, which is
why the push to main did not surface it). Update the two expectations to
include the new keyword.

(cherry picked from commit d5aa23156ce19ce36d95df03953442f83ae6d050)

* Revert "fix(tests): expect follow_redirects in the Jina client kwargs after #5808"

This reverts commit 5bee00bfb09c65a30f77fb4df47a1f82c47ecef7.

* fix(channels): bound deferred Feishu routing by the inbound queue capacity

Review follow-up on #6558: a store outage let every subsequent message for
a chat join the deferred queue with no capacity check (the bus reservation
was only taken after routing succeeded), and each queued message started a
fresh 30s retry budget when it reached the head, so a burst could be
retained for N x 30s and grow without bound.

- Intake is reserved BEFORE routing for every store-backed message
  (bus.reserve_inbound is thread-safe and already used from SDK threads),
  so deferred and live messages share the one configured bound,
  channels.inbound_queue_maxsize; a message that cannot be admitted is
  dropped at once with a warning, never queued or routed as a miss.
- The reservation travels with the message into dispatch (committed by
  _prepare_inbound), is released on the batch path (the flush reserves at
  publish time), on drop after the budget, on a failed deferral, on
  dispatch failure and for every leftover when the drain task is cancelled
  by stop().
- The retry budget runs from the message's arrival: a queued message whose
  budget is spent when it reaches the head is dropped without a lookup.
- The bounded resolver returns the unresolved outcome instead of raising
  it through the tracked task, which logged an ERROR for an expected,
  handled store timeout.
- Upstream's new blocking-io test constructs the store by its old class
  name; it now uses JsonChannelStore.

fix(channels): follow Buzz threads mapped in the connection repository (#6232)
* fix(channels): follow Buzz threads mapped in the connection repository

With channel_connections enabled, ChannelManager stores a bound author's
thread mapping only in the connection repository, but Buzz's thread-follow
gate read only the JSON ChannelStore. engaged_thread was therefore always
False for authors bound with /connect, and every unmentioned reply in a
thread the bot was already answering was silently dropped.

Buzz now resolves the connection identity before the mention gate and looks
the thread up through lookup_thread_id, a helper extracted from
ChannelManager._lookup_thread_id that both sides now share, so the gate and
the manager can no longer disagree about which store owns a mapping.

* fix(channels): drop the manager's own JSON-store read in the skill whitelist

_resolve_available_skill_names fell back to reading the JSON ChannelStore
when the caller's lookup_thread_id found nothing. For a bound message that
lookup is repo-only, so a legacy unbound mapping for the same chat decided
which custom agent's skill whitelist applied. The parameter is now required
and the caller passes "" when nothing is mapped.

Also pin the Buzz thread-follow fix against the real SQL connection
repository (bound through a real /connect) instead of a fake.

* docs(changelog): reference #6232 for the Buzz thread-follow fix

* fix(channels): log Buzz drops of unmentioned replies with no engaged thread

The thread-follow gate was the one drop in _handle_chat_event without a
log line. Log it at DEBUG with the thread root and whether the author was
bound, matching the allowlist drop, so a report that the bot stopped
following replies can be told apart from a lost bind or missing mapping.

Frontend connect flow:
- Open the runtime-config dialog only when a provider still needs
  credentials; configured providers go straight to the connect flow, so
  the binding-code/deep-link path is reachable from the UI again.
- After saving credentials, continue into the connect flow when a user
  binding is still required (multi-user mode) instead of stopping at a
  "Connected" toast.
- Extract shared provider-state helpers to core/channels/provider-state
  and add unit + e2e coverage for the direct-connect and
  configure-then-connect paths.

Provider status semantics:
- Report connection_status from the user's newest connection row;
  with no binding it is not_connected, except in auth-disabled local
  mode where a configured running channel is effectively connected.

Concurrency and event-loop correctness:
- Offload ChannelRuntimeConfigStore construction and writes, channel
  service construction, and Slack connection replies to threads; add a
  tests/blocking_io/ anchor for the runtime-config handlers.
- Consume binding codes with a conditional UPDATE so a code can only be
  used once under concurrent workers; retry upsert_connection as an
  update when a concurrent insert wins the unique constraint.
- Serialize ensure_channel_ready per channel so concurrent provider
  polls cannot double-start a channel worker.

Config and migration hardening:
- Stop mutating the get_app_config()-cached Telegram provider config;
  the runtime store now owns the UI-entered bot username.
- Register channel_connections in STARTUP_ONLY_FIELDS with the
  standardized startup-only Field description.
- Match the legacy unsafe-id bucket by recomputing its exact SHA-1 name
  so another user's same-prefix bucket can never be migrated.
- Remove the unused Telegram process_webhook_update path and document
  src/core/channels in the frontend docs.

* Address PR review comments on authz scoping and channel runtime

Security (review feedback from ShenAC-SAC):
- Scope internal-token callers to the connection owner carried in
  X-DeerFlow-Owner-User-Id instead of bypassing owner checks outright,
  in both require_permission(owner_check=True) and the stateless run
  endpoints. Internal callers keep access to their own and
  shared/legacy threads, and may claim a default-owned channel thread
  for its real owner, but a leaked internal token no longer grants
  cross-user thread access.
- Require admin privileges for POST/DELETE /api/channels/{provider}/
  runtime-config: runtime credentials and channel workers are
  instance-wide shared state (same model as the MCP config API).
  Read-only provider listing stays available to all users.

Performance (review feedback from willem-bd):
- Skip the redundant thread channel-metadata PATCH after the first
  successful backfill per thread.
- Reuse the per-connection Slack WebClient until its token changes
  instead of constructing one per outbound message.
- Reconcile channel readiness for all providers concurrently in
  GET /api/channels/providers.

Also resolve the code-quality unused-import flag in the blocking-io
anchor by pre-importing the channel service via importlib.

* Fix prettier formatting in provider-state test

* Reconcile UI runtime channel config with config reload on restart

Main now reloads a channel's config.yaml entry on restart_channel()
(#3514, issue #3497). Adapt the user-owned connection flow to coexist:

- configure_channel() restarts with reload_config=False — the caller
  just supplied the authoritative config (browser-entered credentials
  that are never written to config.yaml), so a file reload must not
  clobber it with the stale on-disk entry.
- _load_channel_config() re-applies the UI runtime-store overlay used
  at startup, so an operator-triggered restart keeps browser-entered
  credentials for channels without a config.yaml entry and does not
  resurrect a channel disconnected from the UI.
- Offload the reload's disk IO (config.yaml + runtime store) with
  asyncio.to_thread, matching the blocking-IO policy on this branch.
