feat(im): wire Feishu /project channel switching

[lengjingxu]

What

Wire Feishu channel /project command by setting projectSwitching: true and providing the cards.project UI text pack in the Feishu adapter.

Fix: reject stale group-card /project switches when lane mapping is lost (app restart) — fail closed like existing /ctr control actions.

Why

Resolves the Feishu side of #3704 — the shared /project slash command and card action handler are already in place, but the Feishu adapter had not opted in. This commit enables it with the required Chinese UI copy.

Greptile flagged that a stale group card callback could fall back to the operator open_id and switch the DM session instead of the topic lane. Fixed in 229d0d8 by adding the same isGroupCardWithLostLane guard used by control actions.

feat(im): wire Feishu /project channel switching (4b7845e)

• apps/desktop/src/main/im/feishu/adapter.ts — set projectSwitching: true
• apps/desktop/src/main/im/feishu/uiText.ts — add cards.project text pack
• apps/desktop/src/main/im/feishu/__tests__/feishuAdapter.test.ts — 3 tests (flag on, text shape, lane isolation)

fix(im): reject stale group-card /project switches when lane is lost (229d0d8)

• apps/desktop/src/main/im/shared/cardActionHandler.ts — isGroupCardWithLostLane guard on project:switch path; rejectStaleGroupCard accepts optional body
• apps/desktop/src/main/im/shared/types.ts — cards.project.staleGroupCard optional field
• apps/desktop/src/main/im/feishu/uiText.ts — staleGroupCard copy
• apps/desktop/src/main/im/shared/__tests__/cardActionGroupLaneGuard.test.ts — 3 tests (pick fail-closed, dialogue fail-closed, topic lane not falsely blocked)

Verification

• npx vitest run src/main/im — 62 files / 664 tests all pass
• pnpm --filter desktop typecheck — 0 errors
• pnpm check:dco — 2 commits signed
• Live Feishu E2E (requires real bot connection; covered at contract layer by tests)

Dash checklist coverage

#	Item	Status
1	DM /project shows project list	✅ shared listProjectsForControl() + buildProjectPickerCard
2	Group/topic /project scoped to lane	✅ lane-isolated sessionId test
3	Two topics → different projects independently	✅ different lane → different session row
4	Old SDK context cleared on switch	✅ shared switchSessionWorkingDir clears + disposeOneSession
5	Back-to-dialogue uses managed dir	✅ shared project:dialogue path
6	Model/effort/provider/permission preserved	✅ shared switchSessionWorkingDir only touches workingDir + workspaceKind
7	Missing/file directory fails closed	✅ shared fs.statSync().isDirectory() guard
8	Stale/duplicate card clicks	✅ shared project:cancel + attachedUnsupported fallback
9	Stale group card lane loss → fail closed	✅ isGroupCardWithLostLane guard (same as /ctr)

Notes

• Based on main (865ccfb). Coordination with feat(desktop): support Feishu bot working directories #2624 (Feishu working-dir config) will be a follow-up small PR if needed.

Related: #3704
Depends on: #2624 (soft — no merge conflict on main today)

Greptile Summary

This PR enables the shared /project workflow for Feishu and adds the corresponding Chinese card copy and adapter contract tests.

• Enables projectSwitching in the Feishu adapter.
• Adds the complete cards.project UI text pack.
• Adds capability, text-shape, and lane-ID isolation tests.
• The newly reachable card-action path does not reject group/topic callbacks after their in-memory lane mapping is lost.

Confidence Score: 4/5

The PR should not merge until stale Feishu group/topic project-card actions are prevented from switching the operator’s DM session.

Enabling project switching makes a wrong-session update reachable when a card callback outlives its in-memory lane mapping; the handler treats the operator open_id as the target identity instead of failing closed.

Important Files Changed

Filename	Overview
apps/desktop/src/main/im/feishu/adapter.ts	Enables the project-switching flow, but thereby exposes project card actions to stale group/topic callbacks that can fall back to the DM session.
apps/desktop/src/main/im/feishu/uiText.ts	Adds a complete Feishu project-card text pack matching the shared UI contract.
apps/desktop/src/main/im/feishu/tests/feishuAdapter.test.ts	Covers capability wiring, text shape, and session-ID derivation, but not lane loss between card creation and callback handling.

### Issue 1
apps/desktop/src/main/im/feishu/adapter.ts:335
**旧卡片切错会话**

当桌面进程重启、Feishu 客户端重新绑定或 lane 缓存淘汰后，群聊或话题中的旧 `/project` 卡片无法恢复原 lane，回调会保留操作者的 `open_id` 并按私聊身份解析目标，导致项目操作切换私聊会话而非卡片所在的话题会话，同时卡片仍会显示切换成功。项目动作需要像现有 control 动作一样在群卡 lane 丢失时拒绝执行。
