feat: add npm commands for single file operations with minified output

- Add 'npm run checkFile <file>' to run prettier and lint on a single file
- Add 'npm run prettier:file <file>' for formatting individual files
- Add 'npm run lint:file <file>' for linting individual files
- Add 'npm run test:file <file>' for running tests on individual spec files
- Create wrapper scripts that show minimal output on success, full output on errors
- Update CLAUDE.md to emphasize using checkFile command frequently
- Add 25-second timeout for test execution to prevent hanging
