## Why
Graceful shutdown rejects new sessions with an invalid-request error. Give clients a structured shutdown reason and show command center users why session creation is paused.
## What changed
- Add `data: {"reason":"serverShuttingDown"}` to app-server shutdown admission errors while retaining JSON-RPC code `-32600`.
- Show a dedicated shutdown message explaining the wait for active turns and automatic reconnection for non-embedded servers. Recognize older servers by their exact draining message only when error data is absent, and preserve retained-worktree cleanup guidance.
- Keep the command center reconnect presentation when a shutdown error covers the initial overview and no conversation is open.
## Testing
Extend admission and WebSocket shutdown assertions, add embedded and daemon shutdown message snapshots, and cover reconnection with a shutdown error over the initial command center.

## Why
The command center's shortcut footer consumes several rows in narrow terminals, leaving less space for tasks. The overview also ignores attempts to dismiss it with `Esc`.
## What changed
- Keep primary actions in a single-line footer and show task and navigation shortcuts in a `?` help view.
- Respect configured bindings, suppress conflicting hints, and ignore key repeats when toggling help.
- Let the configured cancel key close help or cancel search and rename before dismissing the overview.
- Track overview dismissal while disconnected and clear stale connection notices after reconnecting.
- Use picker defaults for task action and error dialogs, and the theme accent color for agent status titles.
## Testing
Add coverage for help rendering, cancel navigation, custom shortcut conflicts, and overview dismissal during reconnection. Update snapshots for the compact footer and narrow layouts.

## What changed
- Remove the legacy selection-list appearance and use shared full-width selection, filled tabs, wrapped hints, and separate overflow rows throughout.
- Give resume and fork pickers separate toolbar and search rows. Collapse spacing on short screens, keep the focused toolbar control visible on narrow screens, and prioritize labeled primary actions in the footer.
- Apply shared selection styling and contrast-aware text colors to session rows and metadata. Clear inherited selection colors and reversal from the transcript loading overlay.
- Preserve clipped-header notices alongside results in small approval dialogs.
## Testing
Add rendering assertions and snapshots for session selection contrast, reversed selection, loading overlay styles, compact metadata and action labels, and keyboard-focused toolbar visibility. Extend approval clipping snapshots to shorter terminal heights.

## Why
Menu layouts and hints vary across TUI flows, and mismatched measurement and rendering widths can clip subsequent choices when descriptions wrap.
## What changed
- Apply shared picker styling across selection menus, with stable columns, descriptions hidden when space is tight, and compact hints derived from configured key bindings.
- Measure rows at their actual rendering width, including caller insets, so wrapped options receive enough space.
- Wrap model menu headers and shortcut capture content, and use the shared panel surface for shortcut capture.
- Indicate clipped headers in non-searchable menus and show the configured `view all` shortcut only when the view supplies one.
## Testing
Add regression tests and snapshots for wrapping boundaries, narrow picker layouts, configured selection and cancellation keys, and clipped approval headers. Verify that copy/export actions retain complete payloads and composer drafts.

## What changed
- Replace the inline task composer with a session list: `n` opens a blank session in the selected checkout without sending an initial turn or interrupting running agents.
- Use single-letter action shortcuts and `Enter` to open a session. `Esc` cancels search or rename without closing the list; `Ctrl+C` quits from the list.
- Load destination settings for new sessions while carrying over explicit permission choices. Retain blank sessions and their drafts across navigation until the first turn.
## Testing
Update tests and snapshots for command center navigation, shortcuts, blank draft restoration, destination defaults, permission carryover, and directory trust.
GitOrigin-RevId: bddd04fdbe6ac2f5b7bd70293fd04f673b97ba02
## Why
Command center failures need to remain visible while users retain their task selection and composer draft, including when a task is already managed by another app server.
## What changed
- Show action errors above the retained dashboard with a return option and a clear explanation for tasks open elsewhere.
- Keep the dashboard open until task attachment succeeds, and return to the conversation when selecting the already displayed task.
- Offer “View unsent task” in a pager when restoring a failed submission would overwrite newer input.
- Show task refresh failures inline and clear the notice after a successful refresh.
## Testing
Add regression tests and snapshots for attachment conflicts, preserved selection and drafts, successful attachment, inline refresh recovery, unsent task viewing, and visible action failures.
