feat: enhance file-utils with better Bun integration and comprehensive tests

Improvements to src/utils/file-utils.ts:
- Added 10 new utility functions: isFile, isDirectory, readFileAsBuffer, writeFile, writeFileBuffer, createDir, deleteFile, getFileSize, getFileMtime, listDir
- Use fs.promises.mkdir() for reliable directory creation with recursive support
- Improved error handling with specific error messages
- Added JSDoc comments for all functions
- Replaced .gitkeep hack with proper directory creation

Comprehensive test coverage:
- Added 33 new tests (from 8 to 41 in file-utils.test.ts)
- 100% coverage of new functions with edge cases
- Tests for file I/O, binary data, large files, error conditions
- Tests for directory operations, file metadata, filename utilities
- Total test count increased from 130 to 163 tests (571 assertions)

Updated test/cli/commands/init.test.ts:
- Changed from checking .gitkeep files to verifying isDirectory()
- More robust and future-proof directory verification

All 163 tests pass with improved reliability.
