fix: clamp progressBar to prevent RangeError on overflow, add 10 tests

progressBar() in skill-create-output.js could crash with RangeError when
percent > 100 because repeat() received a negative count. Fixed by
clamping filled to [0, width].

New tests:
- progressBar edge cases: 0%, 100%, and >100% confidence
- Empty patterns/instincts arrays
- post-edit-format: null tool_input, missing file_path, prettier failure
- setup-package-manager: --detect output completeness, current marker
