pakrym-oai 5cc5f12efc Move item event mapping into app-server-protocol (#20299)
## Why

Follow-up to #20291.

The v2 item-event-to-notification translation had been embedded in
`app-server/src/bespoke_event_handling.rs`, which made it hard to reuse
anywhere else. This PR moves that stateless mapping into shared protocol
code so other entry points can produce the same `ServerNotification`
payloads without copying app-server logic.

That also lets `thread-manager-sample` demonstrate the same notification
surface that the app server exposes, instead of only printing the final
assistant message.

## What changed

- move `item_event_to_server_notification` into
`codex-app-server-protocol::protocol::event_mapping`
- keep the mapper tests next to the shared implementation in
`codex-app-server-protocol`
- re-export the mapper from `codex-core-api` so lightweight consumers
can use it without reaching into `app-server-protocol` directly
- simplify `app-server/src/bespoke_event_handling.rs` so it delegates
the stateless event-to-notification projection to the shared helper
- update `thread-manager-sample` to:
  - print mapped notifications as newline-delimited JSON
  - use the shared mapper through `codex-core-api`
- enable the default feature set so the sample exposes the normal tool
surface
- use a `read_only` permission profile so shell commands can run in the
sample without widening permissions

## Testing

- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-core-api`
- `cargo test -p codex-app-server bespoke_event_handling::tests`
- `cargo test -p codex-thread-manager-sample`
- `cargo run -p codex-thread-manager-sample -- "briefly explore the repo
with pwd and ls, then summarize it"`
