feat(subagents): system-maintained delegation ledger to stop redundant re-delegation (#3877) ...

* feat(subagents): add delegations ledger field + reducer to ThreadState

* feat(subagents): pure helpers to derive + format the delegation ledger

* feat(subagents): DelegationLedgerMiddleware records + injects the ledger

* feat(subagents): register DelegationLedgerMiddleware for lead when subagents enabled + docs

* add runtime log

* chore(subagents): make delegation-ledger injection log production-ready

* test(subagents): make delegation-ledger registration tests config-free; refresh ultra replay golden for delegations channel

* refactor(subagents): derive TERMINAL_STATUSES from SUBAGENT_STATUS_VALUES + pin it

Make thread_state's TERMINAL_STATUSES a frozenset over the status contract's
SUBAGENT_STATUS_VALUES instead of a hardcoded literal, so the terminal-status
set can never drift from the contract. Add a pinning test asserting the
derivation and that the non-terminal "in_progress" stays excluded.

Addresses PR #3877 review.
