fix: address fourth round of Copilot review feedback

1. Remove unused script_type parameter from _write_integration_json()
   and all 3 call sites — the parameter was no longer referenced after
   the update-context script removal.

2. Fix _build_context_section() docstring — correct example path from
   '.specify/plans/plan.md' to 'specs/<feature>/plan.md'.

3. Improve .mdc frontmatter-only detection in remove_context_section()
   — use regex to match any YAML frontmatter block (not just the exact
   Speckit-generated one), so .mdc files with additional frontmatter
   keys are also cleaned up when no body content remains.
