chore(sync): absorb upstream through 385e4b6bf

[BegoniaHe]

Summary

Absorb upstream 34743f4adfe666e52422426e792b8ff7c88b92ec..385e4b6bfb87952d78d56ce21fc1caff1e68a85e (4 commits) into this fork. Cursor is now 385e4b6bfb87952d78d56ce21fc1caff1e68a85e.

Adapted AstrBotDevs#9887, AstrBotDevs#9885, AstrBotDevs#9851, and AstrBotDevs#9653. No cherry-picks and no skips. Version is 4.27.6; user-visible notes are in changelogs/v4.27.6.md.

This branch also has three later fork commits: WebChat coalesce/regenerate fixes that overlap #6, and a PluginPageHost Vitest timeout fix.

Related issue

None. Upstream synchronization.

Surfaces

• upstream-sync.yaml, upstream-decisions.jsonl
• pyproject.toml, astrbot/__init__.py, uv.lock, CHANGELOG.md, changelogs/v4.27.6.md
• .github/workflows/codeql.yml
• platform adapters/events, plugin service, Respond stage
• bilingual Lark and get_group docs
• Dashboard pluginPageHost.vitest.ts

Implementation notes

• fix(plugin): detect updates for plugins without persisted install sources AstrBotDevs/AstrBot#9887: plugin list payloads use online_version. Default-market updates match by repo then name without persisting implicit install-source records.
• chore(deps): bump github/codeql-action from 4.37.8 to 4.37.9 in the github-actions group AstrBotDevs/AstrBot#9885: CodeQL action pin translated to peeled immutable SHA cdf488f595d80d6e07e03d4674febd5ab45fa938 (v4.37.9).
• feat(platform): enrich group metadata across adapters AstrBotDevs/AstrBot#9851: inbound group metadata enrichment on current adapter boundaries. get_group copies inbound Group. LINE fills name/count only. Slack/Lark/KOOK/Mattermost member pagination is hard-capped. Telegram avatars use the file base URL. DingTalk uses getattr for conversation_title. Slack inbound conversion still skips conversations_info.
• fix: skip the respond stage on an empty message chain AstrBotDevs/AstrBot#9653: empty non-streaming chains skip Respond without logs, receipts, or after-send hooks.
• Extra on this branch, not part of the upstream interval:
  • fix(pipeline): skip empty completion for coalesced fragments
  • fix(dashboard): allow regenerate without conversation checkpoint (overlaps fix(webchat): preserve coalesced replies and retry failed turns #6; fix(webchat): preserve coalesced replies and retry failed turns #6 also has the edit/thread follow-up)
  • test(dashboard): import PluginPageHost outside the 5s budget

Did not re-run make check or the full pytest suite for this PR.

Compatibility and risk

No fork-owned publish/docs URLs restored. Residual risk: adapter group-metadata pagination caps, Slack deferred conversations_info, and merge overlap with #6 on the two shared WebChat commits.

Checklist

• Conventional Commit type is chore, build, ops, or test (not ci).
• The change is focused and does not include unrelated product refactors.
• A toolchain upgrade updates every matching declaration, workflow, image build, and lockfile.
• Runtime Python deps update pyproject.toml, requirements.txt, and uv.lock together.
• I ran the relevant formatting, lint, build, and test commands.
• No secrets committed.
• I did not restore legacy shims, Python <3.14 fallbacks, or upstream publish/docs URLs as fork artifacts.
• I will not merge this PR myself. Merge needs a human maintainer review plus a separate AI-assisted review (AI_POLICY.md).
• AI use follows AI_POLICY.md. Keep exactly one author note below. Do not fabricate the other.

Agent note

Goal: open a PR for sync/upstream-385e4b6bf against master. fix/webchat-turn-handling is already #6.

Paths: platform adapters/events, plugin service, Respond stage, CodeQL workflow, bilingual docs, 4.27.6 changelog, upstream-sync.yaml, upstream-decisions.jsonl, plus later WebChat coalesce/regenerate and PluginPageHost test commits on this branch.

Checks run: focused pytest and make check-yaml recorded on integration commits; PluginPageHost Vitest 5 passed after the static-import change. Residual risk: full make check / make test not re-run here; #6 overlaps two commits on this branch.

Tools: grok-4.6 in opencode.
