Recover assistant turns that complete tool work without producing a visible final answer, while preserving intentional silent replies.
Use concrete tool-instance replay safety across embedded, Codex, and Copilot runtimes so unknown, mutating, async-started, and durable recall operations fail closed. Preserve genuine empty Codex final items without promoting commentary or tool-progress echoes.
Supersedes #90872. Thanks @fuller-stack-dev.

* fix(reply): deliver final reply when queued follow-up claims session; scope dedupe to routed thread
Two core bugs caused composed replies to be silently dropped (no delivery,
no error) when a second message arrived in the same thread mid-run:
1. dispatch-from-config: ensureDispatchReplyOperation only kept the
dispatch-owned operation authoritative while it had no result. Once
runReplyAgent completed the operation to drain queued follow-ups, a
second same-thread inbound could claim the session and the first final
reply would try to re-acquire the lane instead of finishing delivery,
deadlocking behind the queued work. Keep the dispatch-owned operation
authoritative through final delivery.
2. reply-payloads-dedupe: messaging-tool reply dedupe compared only the
channel target, not the routed thread, so a send in one thread could
suppress a later reply in a different thread. Thread the routed thread
id through buildReplyPayloads + follow-up delivery and only fall back to
channel-only matching for providers without a thread-aware suppression
matcher when neither side carries thread evidence.
Adds regression tests; existing Telegram topic-suppression behavior is
preserved by gating the thread guard to providers lacking a plugin matcher.
