fix(feishu): fetch thread context so AI can see bot replies in topic threads (#45254)

* fix(feishu): fetch thread context so AI can see bot replies in topic threads

When a user replies in a Feishu topic thread, the AI previously could only
see the quoted parent message but not the bot's own prior replies in the
thread. This made multi-turn conversations in threads feel broken.

- Add `threadId` (omt_xxx) to `FeishuMessageInfo` and `getMessageFeishu`
- Add `listFeishuThreadMessages()` using `container_id_type=thread` API
  to fetch all messages in a thread including bot replies
- In `handleFeishuMessage`, fetch ThreadStarterBody and ThreadHistoryBody
  for topic session modes and pass them to the AI context
- Reuse quoted message result when rootId === parentId to avoid redundant
  API calls; exclude root message from thread history to prevent duplication
- Fall back to inbound ctx.threadId when rootId is absent or API fails
- Fetch newest messages first (ByCreateTimeDesc + reverse) so long threads
  keep the most recent turns instead of the oldest

* fix(feishu): skip redundant thread context injection on subsequent turns

Only inject ThreadHistoryBody on the first turn of a thread session.
On subsequent turns the session already contains prior context, so
re-injecting thread history (and starter) would waste tokens.

The heuristic checks whether the current user has already sent a
non-root message in the thread — if so, the session has prior turns
and thread context injection is skipped entirely.

* fix(feishu): handle thread_id-only events in prior-turn detection

When ctx.rootId is undefined (thread_id-only events), the starter
message exclusion check `msg.messageId !== ctx.rootId` was always
true, causing the first follow-up to be misclassified as a prior
turn. Fall back to the first message in the chronologically-sorted
thread history as the starter.

* fix(feishu): bootstrap topic thread context via session state

* test(memory): pin remote embedding hostnames in offline suites

* fix(feishu): use plugin-safe session runtime for thread bootstrap

CHANGELOG.md

@@ -22,6 +22,7 @@ Docs: https://docs.openclaw.ai
 - Agents/usage tracking: stop forcing `supportsUsageInStreaming: false` on non-native openai-completions endpoints so providers like DashScope, DeepSeek, and other OpenAI-compatible backends report token usage and cost instead of showing all zeros. (#46142)
 - Node/startup: remove leftover debug `console.log("node host PATH: ...")` that printed the resolved PATH on every `openclaw node run` invocation. (#46411)
 - Control UI/dashboard: preserve structured gateway shutdown reasons across restart disconnects so config-triggered restarts no longer fall back to `disconnected (1006): no reason`. (#46532) Thanks @vincentkoc.
+- Feishu/topic threads: fetch full thread context, including prior bot replies, when starting a topic-thread session so follow-up turns in Feishu topics keep the right conversation state. Thanks @Coobiw.
 - Browser/profiles: drop the auto-created `chrome-relay` browser profile; users who need the Chrome extension relay must now create their own profile via `openclaw browser create-profile`. (#45777) Thanks @odysseus0.
