Release v0.2.0

### Added
- **Advanced logging customizations** in `register_exception_handlers`:
  - `log_level`: override verbosity for exception logging.
  - `log_request_context`: toggle to include/exclude request headers in logs.
  - `log_header_keys`: define which headers are logged (default: `x-request-id`, `user-agent`, etc.).
  - `extra_log_fields`: inject custom structured metadata into logs (e.g. `user_id`, masked API keys).
- **Response headers echo** in `register_exception_handlers`:
  - `response_headers=True` → default headers echoed back.
  - `response_headers=False` → no headers echoed.
  - `response_headers=("x-user-id",)` → custom headers echoed.
- `APIException` now accepts header parameters (headers can carry custom values into responses).
- **Mypy** support added for static type checking.
- Improved documentation for `register_exception_handlers` with usage patterns, logging, and examples.

### Changed
- Logging format has been revamped → now more structured, readable, and consistent.
- Error logging now includes richer metadata: request path, method, client IP, HTTP version, etc.

### Fixed
- Swagger/OpenAPI sometimes showed inconsistent error schemas when `data` was missing.
- **File structure cleanup**: imports in `__init__.py` were fixed and simplified.
  The package is now easier to import and fully modular.
- Fixed a type issue where `error_code` was not properly annotated as `BaseExceptionCode`.
