refactor(vscode-ide-companion/cli): consolidate CLI detection and version management

- Replace separate CliDetector, CliVersionChecker, and CliVersionManager classes with unified CliManager
- Remove redundant code and simplify CLI detection logic
- Maintain all existing functionality while improving code organization
- Update imports in dependent files to use CliManager

This change reduces complexity by consolidating CLI-related functionality into a single manager class.
