Rebuild the left nav as a task-centric sidebar (option A, R1)

Why: creation entries were split (project + at sidebar top-left, new
session at bottom-left) and the project tree forced per-project
navigation; the approved option A design makes one primary New Task
entry, organization a view mode, and identity always present.

Evidence:
- New TaskSidebar: single New Task split button (current-project context,
  Cmd-N, secondary menu for new project / new task in project), project
  <-> timeline organization with persisted collapse, pinned section,
  archive view toggle, hover row actions, account footer fed by
  /api/me (embedded mode shows local tenant; logout clears the key),
  workspace icon strip retained (D25 shared list with Cmd-1..9).
- store: tasks = cross-project list via GET /api/conversations; openTask
  switches project context; pin/archive optimistic + refresh; last
  project context persisted; stale conversations field removed.
- tasklist.ts pure helpers + 6 vitest cases; npm run build passes;
  headless walk on the real binary: cross-project open, pinned-first,
  archive hide/show/restore, new-task flow, zero console errors.

Impact: ProjectNav removed; contracts.ts regenerated from core
(pinned/archived); no composer/right-pane changes (D25/D26/D31 intact).
