Update web search citation prompt (#27096)

## Summary

- Update the web search tool prompt to require Markdown links for cited
sources.
- Explicitly tell the model not to use `turnX`-style citations in
responses.

## Context


https://openai.slack.com/archives/C0AU83S0ZQU/p1780964147777649?thread_ts=1780352049.512299&cid=C0AU83S0ZQU

## Test plan

- `git diff --check`
- `python3 scripts/format.py --check` (fails only on Rust formatter
setup: rustup cannot create temp files under `/home/dev-user/.rustup`;
Just and Python formatter checks pass when using temp cache dirs)
