* fix(gateway): scope per-run message and event reads to the run's data identity
start_run stamps run-event rows with the raw trusted owner id, but
GET /runs/{rid}/messages and /runs/{rid}/events called the event store with
user_id=AUTO, which resolves to the internal caller's make_safe_user_id form.
On the database event store, owners whose id contains characters outside
[A-Za-z0-9_-] (IM channel ids such as "feishu:owner-777") therefore got an
empty list. The regenerate source-run scan had the same mismatch and fell
back or returned 409.
Pass _run_scope_user_id() explicitly, as the thread message routes already
do (#5448), and add user_id to RunEventStore.list_messages_by_run() so every
backend accepts it like list_messages()/list_events(). Browser and API
sessions keep their per-user filter.
* fix(gateway): scope workspace-changes and archive reads to the run's data identity
The same raw-owner mismatch reached two more run-scoped routes. On the SQL
stores, GET /runs/{rid}/workspace-changes reported no changes because its
event lookup used user_id=AUTO, and GET /runs/{rid}/artifacts/archive
answered 404 because both its run-row lookup and its run.delivery event
lookup did.
Pass _run_scope_user_id() to both, and let get_workspace_changes_response()
forward an explicit user_id to the event store.

* feat(gateway): paginate thread run history (#5282)
GET /api/threads/{thread_id}/runs stays a bare array of the newest 100
runs so LangGraph SDK clients keep working. Add GET /runs/page with a
(created_at, run_id) keyset cursor so callers can walk older history.
* fix(gateway): reject one-sided run history cursors
RunManager.list_by_thread now raises if only one of before_created_at
or before_run_id is set, matching the HTTP 422. Document the per-page
sort cost on the SQL keyset query, and add the missing CHANGELOG
[#5282] link definition.
* fix(gateway): round-trip run page cursors through query strings
Emit next_before_created_at with a Z suffix so '+' is not decoded as a
space. Accept that space, and Z, when parsing. Treat blank cursor
fields as absent and reject a non-ISO before_created_at in RunManager
so a harness caller cannot silently restart at the newest page.
* style(gateway): ruff-format run page cursor files
Collapse the one-sided cursor ValueError and the two before_created_at
asserts so ruff format --check passes at line-length 240.
