pakrym-oai 9289b7cea8 [codex] Move hook request plumbing into hook runtime (#23388)
## Why

`run_turn` was still hand-building hook payloads and lifecycle events
for a couple of hook paths. Most hook call sites already delegate
request construction and event emission to `hook_runtime`, which keeps
turn orchestration focused on model-flow decisions rather than hook
plumbing.

This also keeps the legacy `after_agent` message extraction next to the
legacy hook dispatch instead of leaving response-item walking in
`run_turn`.

## What changed

- Added `run_stop_hooks` in `hook_runtime` to build `StopRequest`, emit
preview start events, run the hook, and emit completion events.
- Added `run_legacy_after_agent_hook` in `hook_runtime` to build and
dispatch the legacy `AfterAgent` hook payload, including extracting
input messages from response items.
- Updated `run_turn` to call the hook runtime helpers and keep only the
resulting continuation/block/stop decisions inline.
- Removed the repeated pending session-start hook check from the run
loop.

## Validation

- `cargo test -p codex-core hook_runtime`
