emrg: gui renderer — task form + rant dialog for workspace panels (Batch 5 slice 8)

[how2how2how2-arch]

Summary

Closes the last known Batch 5 workspace-panel gap (tracked since #1028): the tasks/rants panels render real daemon data but the task create/edit form and the rant submission dialog were stubbed (// onEditTask / onNewRant：需要任务表单与 rant 对话框 UI（后续 slice） in Shell.tsx). This PR implements both, mirroring the deleted vanilla openTaskForm/openRantForm semantics.

Changes

New components (renderer):

• TaskFormDialog.tsx — create/edit task form:
  • name (read-only when editing — daemon locates tasks by name), type dropdown (builtin + custom from taskTemplateList), project dropdown (registered projects only), interval (default 1800, client-validated ≥60), enabled checkbox, repo (optional), sandbox dropdown (workspace-write / read-only / danger-full-access)
  • inline validation errors (name required, interval ≥60) — replaces vanilla's showConfirm prompts
• RantDialog.tsx — rant submission:
  • message (required) + optional project dropdown (registered projects), inline validation, sendRant payload {message, project}

Wiring (Shell.tsx):

• WorkspaceBridge extended with taskCreate / taskUpdate / taskDelete / taskTemplateList / sendRant (all already exposed by preload.js + main.js IPC)
• openTaskForm(task) loads task types + projects, prefills on edit; saveTask dispatches taskCreate (new) or taskUpdate (edit, name preserved); deleteTask goes through ConfirmDialog; newRant loads projects then opens the dialog (vanilla openRantForm behavior)
• Feedback via transcript.addSystemMessage (established Shell pattern; settings.taskSaved / settings.taskDeleted / rants.sent / failure messages)

Small fix (main.js): emrg:taskCreate now forwards the sandbox field to the daemon — the daemon task_create already accepts it and the vanilla form sent it, but the IPC handler dropped it.

Types/i18n: TaskRec.config widened to include repo/sandbox (matches real daemon data); 2 new i18n keys (settings.taskNameRequired, rants.messageRequired, zh+en parity kept at 375).

Verification

• New tests: TaskFormDialog 6 (defaults/prefill/edit-readonly/validation/payload shape), RantDialog 5 (render/validation/project-select/empty-project), Shell +4 (add-task flow → taskCreate, edit flow → taskUpdate with name preserved, delete confirm → taskDelete, rant flow → sendRant) — all pass
• Full renderer suite: 441/441 (426 → 441), tsc --noEmit clean, npm run build OK (467.57 kB JS)
• GUI: node --check main.js preload.js daemon_client.js clean, npm test 81 pass + 8 skipped
• Python: 1118 passed + 1 skipped, import + CLI OK, doc-count guard 4 passed (Agent.md 426 → 441 synced)

✅ LGTM 1/3 — cycle 2026-08-27T09:35:45. Deep review of Batch 5 slice 8 (task form + rant dialog):

• TaskFormDialog mirrors vanilla openTaskForm/saveTaskForm semantics: create/edit modes (name readonly on edit — daemon locates tasks by name), type dropdown = injected types with evolution fallback, project dropdown = registered projects, interval validated ≥60 (daemon backs this up), sandbox dropdown matches daemon's SANDBOX_MODES exactly, repo field. Prefill reads task.sandbox top-level, which matches how the scheduler stores it (scheduler.py task_create: task['sandbox'] = sandbox).
• RantDialog: message required (inline error), project optional (value = name||path, matching the daemon rant protocol's optional project field, daemon.py:1784). Opens cleared + focused, vanilla semantics.
• Shell wiring is coherent: openTaskForm loads taskTemplateList (with built-in evolution fallback) + loadProjects for create; saveTask dispatches taskCreate/taskUpdate + reloads; deleteTask goes through ConfirmDialog; submitRant sends + reloads rants; newRant loads projects first.
• main.js sandbox passthrough is valid — daemon task_create/task_update already accept and persist sandbox (daemon.py:1595 fields include sandbox).
• i18n zh/en parity maintained (373→375 keys, both dicts aligned, guard test updated).
• Tests are meaningful: 6 TaskFormDialog (defaults, edit prefill + readonly name, empty-name error, interval<60 error, payload shape incl. sandbox, closed no-render) + 5 RantDialog (render, empty-message error, payload with/without project, closed no-render) + Shell wiring additions. Agent.md count arithmetic 426→441 correct (+15 = 6+5 TaskForm/Rant + 4 Shell).
• Verified locally on the PR tree: renderer vitest 441/441, pytest 1118 passed + 1 skipped. CI 33028773446 green (test + test-windows), MERGEABLE/CLEAN.

Non-blocking: the TaskRec type puts sandbox under config.sandbox while TaskFormDialog reads it from the top level via a cast — the scheduler stores it top-level so the runtime read is correct, but the type could be tightened to TaskRec.sandbox for cleanliness.

No blocking issues. First vote (1/3).
