emrg: restore task-row "Open Session" button in React GUI (vanilla #924 regression)

[argszero]

Summary

The React GUI (v0.2.85) task-management rows lost the "Open Session" button that vanilla (v0.2.65, #924) had — each row now only shows Trigger/Edit/Delete. The daemon still returns project / project_path / session_id from TaskHandler.status(); only the Batch 5 React migration dropped them.

Changes

• renderer/src/lib/workspaceView.ts — TaskRec gains project? / project_path? / session_id? (the daemon status() payload fields lost in the migration).
• renderer/src/components/WorkspaceView.tsx — TaskList inserts an "Open Session" button right after Trigger (vanilla order: Trigger → Open Session → Edit → Delete), disabled when the task has no session_id, click bubbles onOpenSession(task). New onOpenSessionTask prop wired through.
• renderer/src/components/Shell.tsx — openTaskSession handler calls the existing emrg:switchSession bridge with { sessionId: task.session_id, projectPath: task.project_path } (bridge type extended with optional projectPath, matching main.js), then setActiveSid + returns to the sessions view (vanilla emrg: fix open-session returning to session view + add GitHub issue path to promotion feedback #932 lesson: from the task panel the view must switch back to chat, otherwise it looks like nothing happened). Failures surface via the openSession.loadFailed system message.
• Tests — WorkspaceView task-list test asserts 4-button order, disabled state without session_id, and the open-session click callback; Shell wiring test clicks Open Session → switchSession called with sessionId+projectPath → panel returns to the sessions view.
• Agent.md — renderer test count 448 → 449 (Shell 25 → 26).

The settings.taskOpenSession i18n key (zh 打开会话 / en "Open session") already existed but was an orphan — it is now referenced again.

Verification

• Renderer: vitest run 449/449 passed, tsc --noEmit clean, vite build OK
• GUI (main process): 87 pass / 8 skip
• Python: pytest 1147 passed + 1 skipped (1148, matches Agent.md), import + CLI green

✅ LGTM — cycle 20260828-115726

Reviewed the full diff against the rant's acceptance criteria (2026-08-28T11:16:47, vanilla #924 regression):

1. TaskRec type now carries project/project_path/session_id (daemon status() payload) ✓
2. TaskList inserts the Open Session button after Trigger (vanilla 4-button order), disabled without session_id, click bubbles onOpenSession(task) ✓
3. Shell wires openTaskSession → existing emrg:switchSession bridge with { sessionId, projectPath }, then setActiveSid + returns to the sessions view (vanilla #932 lesson) ✓
4. Tests: WorkspaceView asserts 4-button order + disabled state + click callback; Shell asserts switchSession payload + view return ✓
5. Orphan i18n key settings.taskOpenSession re-referenced (was the migration-loss trace) ✓

CI: test + test-windows both green (run 33140765367). Local verification matches: renderer vitest 449/449, tsc clean, vite build OK, GUI 87 pass/8 skip, pytest 1147+1.

✅ LGTM — cycle 20260828-121342

Independent re-review of head bbd7a99 (unchanged since cycle 115726, CI green on this head):

• TaskRec gains session_id/project/project_path — matches daemon TaskHandler.status() payload (scheduler.py status() returns all three; verified against source).
• TaskList renders the Open Session button between Trigger and Edit (vanilla #924 4-button order), disabled when session_id is missing, click bubbles onOpenSession(task) — matches vanilla dialogs.js renderTaskList semantics.
• Shell wiring calls the existing emrg:switchSession bridge with {sessionId, projectPath} then setActiveSid + returns to sessions view (vanilla #932 lesson); error path surfaces openSession.loadFailed.
• Tests cover 4-button order, disabled state, click callback, and the Shell bridge payload + view return.
• Agent.md renderer count 448 -> 449 matches the static guard (test_renderer_count_matches_docs).

Verification recorded last cycle on this exact head: renderer vitest 449/449, tsc clean, vite build OK, GUI 87 pass/8 skip, pytest 1147 passed + 1 skipped (1148 == Agent.md), import + CLI green. CI test + test-windows both pass (run 33140765367).

✅ LGTM — cycle 20260828-122032

Third independent review (head bbd7a99 unchanged, CI test + test-windows green on this head, MERGEABLE). Full diff re-verified this cycle against the rant's acceptance criteria:

1. TaskRec carries session_id/project/project_path — matches daemon TaskHandler.status() payload.
2. TaskList renders the Open Session button after Trigger (vanilla #924 4-button order), disabled without session_id, click bubbles onOpenSession(task).
3. Shell openTaskSession calls emrg:switchSession with { sessionId, projectPath } then setActiveSid + returns to sessions view (vanilla #932 lesson); errors surface openSession.loadFailed.
4. Tests: 4-button order + disabled state + click callback (WorkspaceView), bridge payload + view return (Shell).
5. Agent.md renderer count 448 -> 449 consistent with the static doc-count guard.

3 consecutive LGTMs from distinct cycles (115726, 121342, 122032), no ❌ — merging.
