refactor: consolidate file path validation patterns and support scoped packages

- Extract file path validation regex into ValidationPatterns::FILE_PATH_PATTERN constant
- Add filePathRules() and filePathMessages() helper methods for reusable validation
- Extend allowed characters from [a-zA-Z0-9._\-/] to [a-zA-Z0-9._\-/~@+] to support:
  - Scoped npm packages (@org/package)
  - Language-specific directories (c++, rust+)
  - Version markers (v1~, build~)
- Replace duplicate inline regex patterns across multiple files
- Add tests for paths with @ symbol and tilde/plus characters
