Stop uploading accepted line fingerprints (#22180)

## Summary
- keep accepted-line diff parsing and fingerprint hashing logic locally
- stop uploading path/line hash fingerprints in the accepted-line
analytics event payload
- keep aggregate accepted added/deleted line counts in the event

## Testing

 7. Use inline numbered references where a row or bullet points to issues, for example `Compaction bugs [1](https://github.com/openai/codex/issues/123), [2](https://github.com/openai/codex/issues/456)`. Do not add a separate footnotes section.

 9. Mention the collector `script_version`, repo checkout `git_head`, and time window in one compact source line. In default mode, put this before the details prompt so the final line still asks whether the user wants details. In details-upfront mode, it can be the footer.

 ## Attention Markers
 
-The collector scales attention markers by the requested time window. The baseline is 5 human user interactions for `🔥` and 10 for `🔥🔥` over 24 hours; longer or shorter windows scale those cutoffs linearly and round up. For example, a one-week report uses 35 and 70 interactions. Human user interactions are human-authored new issue posts, human-authored new comments, and human reactions created during the window, including upvotes. Bot posts and bot reactions are excluded. In prose, explain this as high user interaction rather than naming the emoji.

+
+> `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 and app-server is already running. After a successful fetch, the updater restarts app-server with the refreshed binary and only then replaces its own process image. |
+| Some other tool updates the managed binary path | The next fresh start or restart uses the updated file at that path | Only if `bootstrap` is active, because the updater still runs `install.sh` on its normal cadence. | Without `bootstrap`, no. With `bootstrap`, the next successful updater pass compares the managed binary contents after `install.sh` runs; if app-server is running and they differ from the updater's current image, it refreshes app-server first and then itself. |
+
+### 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`
+- after a successful refresh, if app-server is running and the managed binary
+  contents changed, the updater restarts app-server with that binary first and
+  only then replaces its own process image
+- 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 the managed binary path:
+
+- without `bootstrap`, a currently running app-server remains on the old
+  executable image until an explicit `restart`
+- with `bootstrap`, the detached updater loop notices the changed managed
+  binary on its next successful scheduled pass after running `install.sh`; if
+  app-server is running, it refreshes app-server first and then refreshes itself
+  once that replacement starts successfully
+
+## 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.
+
+Top-level `codex remote-control` bootstraps with `--remote-control` when the
+updater loop is not running. Otherwise it enables remote control and starts the
+daemon normally.
+
+`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
