feat: v0.4.0 - Architecture refactor, bug fixes, and quality improvementsfeat/architecture-and-quality-improvements

- Fixed #25: config_file_save/load now include path: [] in payload
- Added exception hierarchy (SDKError, HttpError, ApiError, ValidationError)
- Added utility functions (json, ids, paths)
- Added structured logging with request ID tracking
- Added optional Pydantic validation models
- Refactored to pyvyos.core.* structure with backward compatibility shims
- Moved JSON specs to docs/development/vyos_api/
- Added comprehensive test suite (19 shim tests, 16 utils tests, 6 exception tests)
- Updated pyproject.toml for uv sync editable installation
- Added development documentation (architecture, roadmap, quality guidelines)

Maintains 100% backward compatibility with 0.3.0
