* fix(cli): respect --no-interactive flag in validate command
The validate command's spinner was starting regardless of the
--no-interactive flag, causing hangs in pre-commit hooks.
Changes:
- Pass noInteractive option to runBulkValidation
- Handle Commander.js --no-* flag syntax (sets interactive=false)
- Only start ora spinner when in interactive mode
- Add CI environment variable check to isInteractive() for industry
standard compliance
* test: add unit tests for interactive utilities and CLI flag
- Export resolveNoInteractive() helper for reuse
- Add InteractiveOptions type export for testing
- Refactor validate.ts to use resolveNoInteractive()
- Add 17 unit tests for isInteractive() and resolveNoInteractive()
- Add CLI integration test for --no-interactive flag
This prevents future regressions where Commander.js --no-* flag
parsing is not properly handled.
