Abhinav 93d53f655b Add /hooks browser for lifecycle hooks (#19882)
## Why

`hooks/list` and `hooks/config/write` give us read/write access to hooks
and their state. This hooks up the TUI as a client so users can inspect
and manage that state directly.

## What

- add a two-page `/hooks` browser in the TUI: an event overview with
installed/active counts, followed by a per-event handler page with
toggle controls and detail rendering
- thread managed-state metadata through hook discovery and `hooks/list`
so the UI can label admin-managed hooks and suppress toggles for them
- persist hook toggles through the existing config-write path and add
snapshot coverage for the event list, handler list, managed-hook, and
empty states

## Stack

1. openai/codex#19705
2. openai/codex#19778
3. openai/codex#19840
4. This PR - openai/codex#19882

## Reviewer Notes

- Main UI logic is in
`codex-rs/tui/src/bottom_pane/hooks_browser_view.rs`; most of the diff
is the new view plus its snapshot coverage
- Request / write plumbing for opening the browser and persisting
toggles is in `codex-rs/tui/src/app/background_requests.rs` and
`codex-rs/tui/src/chatwidget/hooks.rs`
- Outside the TUI, the only behavioral change in this PR is threading
`is_managed` through hook discovery and `hooks/list` so managed hooks
render as non-toggleable
- The `codex-rs/tui/src/status/snapshots/` churn is unrelated merge
fallout from the stacked base branch's newer permission-label rendering

codex-protocol

This crate defines the "types" for the protocol used by Codex CLI, which includes both "internal types" for communication between codex-core and codex-tui, as well as "external types" used with codex app-server.

This crate should have minimal dependencies.

Ideally, we should avoid "material business logic" in this crate, as we can always introduce Ext-style traits to add functionality to types in other crates.
