Artifact: Plan-Mode Read-Only Pass

A read-only planning pass on a multi-file task before any edits are allowed -- exercises co-09.

[PLAN MODE -- read-only, no write/edit tools available]
1. read_file(path="src/api/router.py")
2. read_file(path="src/api/middleware/__init__.py")
3. grep(pattern="rate", path="src/")
4. read_file(path="requirements-info.md")
 
Proposed plan:
  1. Add RateLimitMiddleware to src/api/middleware/rate_limit.py
  2. Register it in router.py's middleware stack
  3. Add config for requests-per-minute in settings.py
  4. Add tests: test_rate_limit.py covering under-limit, at-limit, over-limit

Verify: all four logged actions (read_file x3, grep x1) are read-only; zero edit_file or write_file calls appear anywhere in the transcript -- satisfying ex-11's rule that no file is modified during the planning pass.
