feat: strengthen tool emulation prompting

Improve proxy-side tool instructions so models more reliably emit structured tool actions, and add focused tests covering prompt guidance and default action limits.

+## Handoff: team-plan → team-exec
+- **Decided**: The next compatibility-first phase is contract freeze/alignment, not another runtime extraction: tighten tests around the actual tool-call support level, then align schema/docs wording to match.
+- **Rejected**: No new `app/main.py` refactor in this slice, and no Anthropic streaming fallback implementation; that would turn the phase into a behavior change instead of a compatibility sync-up.

+## Handoff: team-verify → complete
+- **Decided**: This phase only extracts tooling-policy helpers out of `app/main.py` into `app/http/tooling_policy.py`; OpenAI / Anthropic tool allowlist, `tool_config`, and tooling-context behavior stay unchanged.
+- **Rejected**: No protocol/runtime behavior change, no stream/non-stream bridge rewrite, and no session-cache or ask-mode semantic change beyond moving helper definitions.
+- **Risks**: The new helper takes `settings` explicitly, so any future callers must pass the gateway settings object; if tooling policy expands later, keep helper/module boundaries aligned with the existing bridge regression suite.
+- **Files**: `app/main.py`, `app/http/tooling_policy.py`
