Merge branch 'main' into dev/cc/new-schema

## Why

The app-server watcher relocation leaves the generic filesystem watcher
as the last watcher-specific implementation still living inside
`codex-core`. Moving that code to a small crate keeps `codex-core`
focused on thread execution and lets app-server depend on the watcher
without reaching back into core for filesystem watching primitives.

This PR is stacked on #21287.

## What changed

- Added a new `codex-file-watcher` crate containing the existing watcher
implementation and its unit tests.
- Updated app-server `fs_watch`, `skills_watcher`, and listener state to
import watcher types from `codex-file-watcher`.
- Removed the `file_watcher` module and `notify` dependency from
`codex-core`.
- Updated Cargo workspace metadata and `Cargo.lock` for the new internal
crate.

## Validation

- `cargo check -p codex-file-watcher -p codex-core -p codex-app-server`
- `cargo test -p codex-file-watcher`
- `cargo test -p codex-app-server
skills_changed_notification_is_emitted_after_skill_change`
- `just bazel-lock-update`
- `just bazel-lock-check`
- `just fix -p codex-file-watcher`
- `just fix -p codex-core`
- `just fix -p codex-app-server`

 - When writing tests, prefer comparing the equality of entire objects over fields one by one.

 - Prefer private modules and explicitly exported public crate API.

+# codex-app-server-daemon
+
+> `codex-app-server-daemon` is experimental and its lifecycle contract may
+> change while the remote-management flow is still being developed.
+
+`codex-app-server-daemon` backs the machine-readable `codex app-server`
+lifecycle commands used by remote clients such as the desktop and mobile apps.
+It is intended for Codex instances launched over SSH, including fresh developer
+machines that should expose app-server with `remote_control` enabled.
+
+## Platform support
+
+The current daemon implementation is Unix-only. It uses pidfile-backed
+daemonization plus Unix process and file-locking primitives, and does not yet
+support Windows lifecycle management.
+
+## Commands
+
+```sh
+codex app-server daemon start
+codex app-server daemon restart
+codex app-server daemon enable-remote-control
+codex app-server daemon disable-remote-control
+codex app-server daemon stop
+codex app-server daemon version
+codex app-server daemon bootstrap --remote-control
+```
+
+On success, every command writes exactly one JSON object to stdout. Consumers
+should parse that JSON rather than relying on human-readable text. Lifecycle
+responses report the resolved backend, socket path, local CLI version, and
+running app-server version when applicable.
+
+## Bootstrap flow
+
+For a new remote machine:
+
+```sh
+curl -fsSL https://chatgpt.com/codex/install.sh | sh
+$HOME/.codex/packages/standalone/current/codex app-server daemon bootstrap --remote-control
+```
+
+`bootstrap` requires the standalone managed install. It records the daemon
+settings under `CODEX_HOME/app-server-daemon/`, starts app-server as a
+pidfile-backed detached process, and launches a detached updater loop.
+
+## Installation and update cases
+
+The daemon assumes Codex is installed through `install.sh` and always launches
+the standalone managed binary under `CODEX_HOME`.
+
+| Situation | What starts | Does this daemon fetch new binaries? | Does a running app-server eventually move to a newer binary on its own? |
+| --- | --- | --- | --- |
+| `install.sh` has run, but only `start` is used | `start` uses `CODEX_HOME/packages/standalone/current/codex` | No | No. The managed path is used when starting or restarting, but no updater is installed. |
+| `install.sh` has run, then `bootstrap` is used | The pidfile backend uses `CODEX_HOME/packages/standalone/current/codex` | Yes. Bootstrap launches a detached updater loop that runs `install.sh` hourly. | Yes, while that updater process is alive. After a successful fetch, it restarts a currently running app-server only when the managed binary reports a different version. |
+| Some other tool updates the managed binary path | The next fresh start or restart uses the updated file at that path | No | Not automatically. The existing process keeps the old executable image until an explicit `restart`. |
+
+### Standalone installs
+
+For installs created by `install.sh`:
+
+- lifecycle commands always use the standalone managed binary path
+- `bootstrap` is supported
+- `bootstrap` starts a detached pid-backed updater loop that fetches via
+  `install.sh`, then restarts app-server if it is running on a different version
+- the updater loop is not reboot-persistent; it must be started again by
+  rerunning `bootstrap` after a reboot
+
+### Out-of-band updates
+
+This daemon does not watch arbitrary executable files for replacement. If some
+other tool updates a binary that the daemon would use on its next launch:
+
+- a currently running app-server remains on the old executable image
+- `restart` will launch the updated binary
+- for bootstrapped daemons, the detached updater loop only reacts to updates it
+  fetched itself; it does not watch arbitrary file replacement
+
+## Lifecycle semantics
+
+`start` is idempotent and returns after app-server is ready to answer the normal
+JSON-RPC initialize handshake on the Unix control socket.
+
+`restart` stops any managed daemon and starts it again.
+
+`enable-remote-control` and `disable-remote-control` persist the launch setting
+for future starts. If a managed app-server is already running, they restart it
+so the new setting takes effect immediately.
+
+`stop` sends a graceful termination request first, then sends a second
+termination signal after the grace window if the process is still alive.
+
+All mutating lifecycle commands are serialized per `CODEX_HOME`, so a concurrent
+`start`, `restart`, `enable-remote-control`, `disable-remote-control`, `stop`,
+or `bootstrap` does not race another in-flight lifecycle operation.
+
+## State
+
+The daemon stores its local state under `CODEX_HOME/app-server-daemon/`:
+
+- `settings.json` for persisted launch settings
+- `app-server.pid` for the app-server process record
+- `app-server-updater.pid` for the pid-backed standalone updater loop
+- `daemon.lock` for daemon-wide lifecycle serialization
