## Why
Feature overrides previously forced embedded mode even when they could work with the shared daemon. A running daemon can also have different feature settings from the current invocation, including when the invocation uses defaults.
## What changed
- Allow selected Boolean feature overrides and `suppress_unstable_features_warning` in daemon mode. Keep explicit overrides that disable shared services in embedded mode.
- Pass shared-service feature overrides to newly launched daemons and persist them for restarts and updates without changing a running daemon's settings.
- Check daemon feature settings with `experimentalFeature/list` before attaching. Warn and fall back to embedded mode on mismatches, failed checks, or an incompatible code-mode host fallback policy. Skip this check for the agents overview.
- Resolve worktree configuration before daemon selection and allow worktree sessions to auto-start the daemon.
- Forward `suppress_unstable_features_warning` in thread configuration overrides.
## Testing
Add coverage for override eligibility and precedence, launch-feature persistence and reuse, and TUI fallback warnings for feature and host-policy mismatches. Extend worktree integration coverage to exercise daemon auto-start and warning suppression.

## Why
TUI startup metrics report the selected app-server mode before a connection succeeds, which can misrepresent embedded fallback or failed startup. Daemon startup and update actions also need distinct outcome observations.
## What changed
- Record `codex.tui.start` once after the first connection attempt, using the actual mode or `unconfirmed`, and include daemon selection and auto-start tags.
- Add `codex.daemon.start` for TUI auto-start and `codex.daemon.update` for foreground CLI updates and TUI update handoffs, using existing analytics consent and identity handling.
- Report TUI handoffs as `handoff_requested` and suppress duplicate child reporting. Remove the suppression flag when spawning long-lived daemon processes.
- Tag daemon settings by enabled state and explicit presence, without exporting setting values or contents; report invalid or unreadable settings as `unknown`.
## Testing
Add coverage for analytics defaults and explicit consent overrides, unconfirmed CLI updates, settings presence, and exactly-once launch observations. Extend the worktree TUI test to check startup tags and a single update handoff observation.

## Why
Managed app-server shutdowns use a fixed 60-second grace period. Allow users to adjust how long shutdown waits before forcing the process to exit.
## What changed
- Add `shutdownGraceSeconds` to daemon settings, accepting integers from 0 through 300 and defaulting to 60. Zero requests graceful shutdown and then forces termination immediately.
- Apply the setting to managed app-server stops and restarts, including updater-triggered restarts, and extend the lifecycle lock timeout to accommodate the maximum grace period.
- Keep `stop` usable with unreadable or invalid settings by falling back to the default grace period.
## Testing
Add tests for setting defaults and bounds, invalid-value fallback, preservation when saving remote-control settings, graceful process exit, and forced termination with zero or finite grace periods.

## Why
The managed daemon's updater used a fixed hourly cadence with no saved preference to disable automatic updates.
## What changed
- Read `updater.autoUpdateEnabled` and `updater.updateIntervalMinutes` from `CODEX_HOME/app-server-daemon/settings.json`, defaulting to enabled with a 60-minute interval. Keep the initial five-minute delay and require a positive interval.
- Apply the enabled preference during daemon lifecycle operations and re-read settings before updates and recurring waits. Preserve updater preferences and unknown fields when saving remote-control settings, using atomic file replacement.
- Signal the updater's process group on Unix so stopping it also terminates installer children. Allow daemon shutdown even when settings are malformed.
- Document updater configuration and remote-control preference behavior. Manual `codex update` remains unaffected.
## Testing
Add tests for settings preservation, interval validation, recurring waits, enabling and disabling updates across restart and bootstrap, Unix installer termination, and shutdown with malformed settings.
