emrg: GUI task/template management in settings (rant 2026-08-12T18:23:15 P3)

[argszero]

Summary

Final slice (P3) of rant 2026-08-12T18:23:15 (task generalization + GUI task management). P1 (#709) and P2 (#710, daemon task/template CRUD + hot reload) are already merged; this PR adds the GUI management UI on top of the P2 daemon commands.

Changes

• Settings dialog — scheduled tasks section (#settings-dialog): task list (name / type / project / interval / enabled), plus Add / Trigger / Edit / Delete actions.
• Task form (inline): name, type picker (builtin + custom types), project picker (registered projects only), interval (\u226560 enforced client-side too), enabled toggle, optional repo. Task name is immutable when editing (daemon locates by name).
• Custom task types section: list of builtin (read-only, no action buttons) + custom types (edit / delete / add), prompt-template textarea form.
• IPC + protocol wiring: emrg:taskCreate/Update/Delete and emrg:taskTemplateList/Create/Update/Delete in main.js + preload.js; new RESPONSE_TYPES entries (task_result / templates_list / template_result) in daemon_client.js — without these, sendCommandAndWait falls back to the command name as respType and would time out against the daemon's actual frame types.
• i18n: 26 new keys (zh + en).

6 host-confirmed decision points enforced

1. Builtin types read-only \u2705 (no edit/delete rendered; daemon also refuses)
2. Deleting a referenced custom type refused \u2705 (daemon error surfaces with task count)
3. Project selection limited to registered projects \u2705 (picker = listProjects)
4. Hot reload \u2705 (P2 apply_tasks on every create/update/delete)
5. Interval minimum \u2265 60s \u2705 (client-side validation + daemon validation)
6. Builtin type templates read-only \u2705

Tests

• renderer smoke +4 (task list render + edit\u2192taskUpdate; create with interval validation; custom-type CRUD with builtin read-only)
• daemon_client +1 (RESPONSE_TYPES mirror for the 7 task/template commands, incl. error-frame rejection)
• GUI suite 225\u2192229 all green; pytest 744 green; import + CLI checks green; Agent.md counts synced (emrg: sync test counts to 484 + guard test against doc drift (recurs #426/#430/#510) #511 guard).

✅ LGTM — cycle

Independent re-verification on head a64b573 (11 files, 786+/2-, GUI task/template management P3 of rant 2026-08-12T18:23:15):

1. Protocol wiring — RESPONSE_TYPES adds the 7 task/template commands (task_create/update/delete → task_result, task_template_list → templates_list, template create/update/delete → template_result), mirroring daemon.py handlers from #710. main.js IPC handlers validate name/type/project/prompt as non-empty strings before send, propagate daemon errors via throw, 8s CRUD / 5s list timeouts. preload exposes taskCreate/taskUpdate/taskDelete/taskTemplate{List,Create,Update,Delete}.
2. Task management UI — list rows (name/type badge/project·interval·disabled hints) with trigger (reuses /trigger semantics), edit (form prefill, name disabled since daemon locates by name), delete (confirm dialog → taskDelete → renderTaskList). Form: type dropdown builtin+custom, project dropdown restricted to registered projects (decision ③), interval ≥60 client-side + daemon backstop (decision ⑤), enabled checkbox, optional repo.
3. Template management — builtin types read-only (no action buttons rendered, decision ①⑥); custom templates create/update/delete with prompt preview (60-char truncation), delete-refused error surfaced via system message (decision ②), name immutable on edit.
4. i18n — full zh/en key pairs (30+ keys) for all new strings; static data-i18n in index.html.
5. Regression — ran GUI npm test: 229 passed (was 225, +4: RESPONSE_TYPES coverage + task list render/edit prefill + interval<60 rejection + template builtin-readonly CRUD); pytest 744 passed; doc-count guard green (Agent.md 225→229 breakdown updated correctly: 44 daemon_client + 107 renderer smoke). No issues found.

✅ LGTM — cycle. CI PASS (run 31589657813). Reviewed full diff: task/template CRUD IPC wired to daemon P2 commands, RESPONSE_TYPES entries added (task_result/templates_list/template_result — otherwise sendCommandAndWait falls back to the command name and would time out), settings UI enforces all 6 host decision points (builtin read-only, referenced-type delete refusal surfaced, registered-projects picker, hot reload via apply_tasks, interval >=60 client + daemon, builtin templates read-only), GUI 229 + pytest 744 green, doc counts synced.

✅ LGTM — cycle. Re-verified on head a64b573 (this cycle): full diff 11 files 786+/2- — task/template CRUD IPC (main.js+preload.js), RESPONSE_TYPES +7 (task_result/templates_list/template_result — prevents sendCommandAndWait fallback timeout), settings UI enforces all 6 host decisions (builtin read-only, referenced-type delete refusal, registered-projects picker, hot reload, interval >=60, builtin templates read-only). CI PASS 31589657813; local pytest 744 + GUI 229 green. No issues.
