## Why
`codex app-server daemon update` previously required a latest-channel installation, leaving pinned and local managed packages unable to return to production updates through that command.
## What changed
- Allow explicit updates to restore managed packages to the latest stable release while preserving the automatic-update preference. Extend legacy migration to local and pinned packages when the published installer and release support it.
- Bind restoration to the selected release with a single-use updater authorization and installer guards. Scheduled updates and ordinary updater socket requests continue to respect pins.
- Restart a running daemon when its selected package changes, even if the binary and version are identical; leave stopped daemons stopped.
- Reject incompatible production packages before selecting them, resolve Windows junction targets for ownership checks, and show the restoration command after installing a pinned CLI package.
## Testing
Extend daemon and installer tests to cover local-package migration, restoration with automatic updates enabled or disabled, same-binary package restarts, stopped-daemon preservation, selection races, incompatible releases, and socket requests that must not undo pins.

## What changed
Add `codex app-server daemon update --from-cli` to copy and pin the invoking CLI's complete package, including downgrades and local builds. Require interactive confirmation or `--yes`, and warn that restarting a running daemon may interrupt work.
Validate and stage the package before stopping the daemon, recheck the selection and running state after confirmation, and restart only a previously running daemon. Migrate legacy daemon installations to the dedicated package directory while preserving the standalone CLI selection. Explicit replacements disable automatic package updates.
## Testing
Add coverage for cancellation, packages changed during confirmation, version pinning, and legacy migration. Extend CLI integration tests to verify noninteractive confirmation requirements, rejection of incomplete packages without stopping the daemon, and successful replacement and restart.
