Improve uv installation feedback and Docker dependency locking

- Track and display which installation method succeeded for uv
- Add --locked flag to Docker uv sync for stricter dependency enforcement
- Users now see "uv installed successfully via Homebrew\!" etc.

This addresses code review feedback about installation transparency
and dependency management strictness.
