feat(directives): strict orchestration flow + sidebar overhaul + task page rewrite (#134)

End-to-end rewrite addressing the issues from the user's UX review.
The system now feels like a daemon-orchestration tool: lock a contract
and the orchestrator just goes; PR raised → auto-ship → reopen for
amendments. The sidebar tree shows real entities only (no duplicates,
no inline action buttons polluting the file list), and every entity
gets a right-click context menu. Task page matches the old /exec
layout (diff on the left, feed + composer on the right).

## Backend — strict lifecycle (the orchestrator-never-spawned bug)

Root cause: `phase_planning()` gates on `directive.status='active'`, but
`start_contract()` only flipped the contract row — the parent directive
stayed in whatever state it was. So locking a contract did nothing
visible.

Fix: contract lifecycle now drives directive status in the same
transaction.

  start_contract   → if contract becomes active, flip directive
                     draft|paused|idle|inactive → active
  pause_contract   → after promote, if no active contract left,
                     directive → paused
  complete_contract→ after promote, if no active left, directive →
                     inactive (also fires on auto-ship from PR detect)
  unlock_contract  → if was active and no active left, directive →
                     paused
  reopen_contract  → NEW. shipped → active. Directive → active,
                     orchestrator_task_id/pr_url/pr_branch cleared so
                     the reconciler spawns a fresh planner. The
                     planner reads get_latest_merged_revision and
                     frames the new plan as an amendment.

handlers::directive_documents lifts state.kick_directive_reconciler()
into run_contract_transition so every successful transition wakes the
reconciler immediately (no 15s wait).

handlers::directives `update_directive` (PR-detection branch) calls
`complete_contract(active_contract_id, pr_url, pr_branch)` instead of
`set_directive_inactive`. The contract auto-ships; the directive
follows via the sync above. No more manual "Mark complete" click.

POST /api/v1/contracts/{id}/reopen added + wired through openapi.

Spawn task names dropped the directive-title prefix that looked
redundant in the sidebar:
  "Plan: <title>"      → "orchestrator"
  "Re-plan: <title>"   → "orchestrator (re-plan)"
  "PR: <title>"        → "completion"
  "Update PR: <title>" → "completion (update)"

## Frontend — sidebar

* De-dupe: DocumentTasksFolder filters tasks[] to exclude any task
  whose id already appears in steps[].taskId. Single row per task,
  single highlight on click.
* Generic SidebarContextMenu (new) replaces the directive-only
  DirectiveContextMenu (deleted). Per-entity item arrays built at the
  page level — directive, contract, step, task each have their own
  contextual actions.
* Right-click works on every sidebar entity now (was directive-only).
* `+ New document` / `+ New ephemeral task` inline buttons removed.
  Reachable via the directive folder right-click OR the hover-only
  `+` button on the directive folder row.
* ContractHeader: dropped "Mark complete" button (auto-fires on PR).
  Added "Reopen for amendment" button when contract is shipped.

## Frontend — task page rewrite

TaskPage.tsx replaces DocumentTaskStream.tsx (deleted). Two-column
layout matches the old /exec page that the user preferred:

  ┌────────────────────────┬──────────────────────────────────┐
  │  Changed files (~30%)  │  Transcript feed (scrollable)    │
  │  ──────────────────    │  ──────────────────────          │
  │  src/foo.rs            │  [user] do thing                 │
  │  src/bar.rs            │  [tool] Read foo.rs              │
  │                        │                                  │
  │  Diff (selected file)  │                                  │
  │                        ├──────────────────────────────────┤
  │                        │  Composer (sticky bottom)        │
  └────────────────────────┴──────────────────────────────────┘

Diff comes from getTaskDiff(); parseDiff + DiffFileView exported from
OverlayDiffViewer for reuse (no duplication). Diff auto-refreshes
when the task transitions to a terminal state. Transcript styling +
sticky composer keep the parts the user liked. "Open in task page"
button removed — the right pane IS the task page.
