emrg: gui renderer — wire workspace panels to real daemon data (projects/tasks/rants + project sessions)

[how2how2how2-arch]

Summary

Wires the workspace panels (projects / tasks / rants) to real daemon data in the React renderer — the last big "stub" from the Batch 5 migration. The WorkspaceView component was fully built with all callbacks and pure logic (lib/workspaceView.ts) but Shell passed empty arrays and the project-sessions sub-view always rendered "no sessions".

Changes

• renderer/src/components/Shell.tsx — the wiring layer:
  • Loads listProjects / listTasks / listRants when the corresponding panel activates (vanilla loadTaskMeta / renderRantList semantics — refresh on every entry).
  • Project sessions sub-view: listProjectSessions({ projectPath }) with loading / empty / error states.
  • Actions wired to the bridge: switch-session (from a project's session list), add-project (pickProjectDir → registerProject → reload), delete-project (ConfirmDialog + removeProject + reload, protected-project errors surfaced), trigger-task (triggerTask + app.triggered system message + reload).
  • Owns a ConfirmDialog via the shared lib/dialog reducer for the delete confirmation.
  • Degradation unchanged: window.emrg absent → no-op loads, empty lists (jsdom / preload-less safe).
• renderer/src/components/WorkspaceView.tsx:
  • New projectSessions / projectSessionsError / currentSid props; ProjectSessions now renders real session rows (title || full id, "current" mark + relative time via sessionRowView, click → select) instead of the static "no sessions" stub.
• renderer/src/components/Shell.test.tsx: +3 tests (tasks panel loads listTasks, rants panel loads listRants, projects panel loads listProjects + session sub-view loads listProjectSessions).
• renderer/src/components/WorkspaceView.test.tsx: +2 tests (sessions sub-view loading → rows → select; empty + error states).
• Agent.md: renderer 421 → 426; Batch 5 workspace description updated.

Verification

• tsc --noEmit clean; vitest426 passed (42 files); npm run build succeeds.
• Full Python suite 1106 passed + 1 skipped; doc-count guard 4 passed; import OK.

Not in scope (future slices)

• Task create/edit form and the "new rant" compose dialog (onEditTask / onNewRant remain unwired no-ops — they need form UI, the bridge methods exist).

Deep review of the workspace data wiring:

• WorkspaceView/Shell: panel-activation loaders (projects/tasks/rants) refresh on every activation (vanilla semantics); project-sessions sub-view has loading/error/empty states; current-sid marker via sessionRowView.
• Actions wired through the real bridge: switchSession (sid validated in main.js), addProject (pickProjectDir + registerProject via implicit list_sessions touch-register, dir writability check), deleteProject (ConfirmDialog + removeProject with protected emrg/emrg-task guard + open-session close), triggerTask (trigger_task + system message feedback).
• All 9 bridge methods exist in preload.js and main.js, mapping to daemon commands list_projects / list_sessions(cwd) / remove_project / list_tasks / trigger_task — production wiring verified end-to-end (not stubs).
• window.emrg missing degrades gracefully (no-op), errors surface via transcript.addSystemMessage.
• Tests: 5 new (3 Shell + 2 WorkspaceView) covering load/render/select/empty/error paths; vitest 426/426 (Agent.md count arithmetic 421→426 = +2 workspaceView +3 Shell correct), tsc clean.
• CI: run 33024025355 test + test-windows green on head 666a924.
