[hooks] use a user message > developer message for prompt continuation (#14867) 
## Summary

Persist Stop-hook continuation prompts as `user` messages instead of
hidden `developer` messages + some requested integration tests

This is a followup to @pakrym 's comment in
https://github.com/openai/codex/pull/14532 to make sure stop-block
continuation prompts match training for turn loops

- Stop continuation now writes `<hook_prompt hook_run_id="...">stop
hook's user prompt<hook_prompt>`
- Introduces quick-xml dependency, though we already indirectly depended
on it anyway via syntect
- This PR only has about 500 lines of actual logic changes, the rest is
tests/schema

## Testing

Example run (with a sessionstart hook and 3 stop hooks) - this shows
context added by session start, then two stop hooks sending their own
additional prompts in a new turn. The model responds with a single
message addressing both. Then when that turn ends, the hooks detect that
they just ran using `stop_hook_active` and decide not to infinite loop

test files for this (unzip, move codex -> .codex):

• Stonpet’s cooked, aloha style: flash-seared over a blue quasiflame, glazed with nebula salt, and
  rested until the hyperspace juices settle.

  Now we eat with gratitude, my friend. One mindful bite in, and the flavor is pure cosmic surf:
  smoky, bright, and totally out of this dimension.
