fix(skills): Fix cc-session project resolution and output formatting

- resolve_project now tries all matching projects, picks first with
  JSONL files (handles multiple matches like old/new project paths)
- resolve_session uses portable ls+grep instead of find -printf
- Fix jq output to use -r flag for proper newline rendering
