feat: ✨ Add request based logging and update dependencies

[faizanazim11]

This pull request introduces several improvements and new features to the Jetpack microservice utility library, focusing on developer experience, code quality, and observability. The most significant changes include enhanced documentation (including a new Copilot instructions file and a changelog), upgrades to logging and response metadata with correlation ID support, improved error handling, expanded testing infrastructure, and updates to dependencies and project configuration.

Documentation & Developer Guidance:

• Added a comprehensive .github/copilot-instructions.md file detailing code style, architecture patterns, testing strategies, file organization, and best practices for contributors and Copilot usage.
• Introduced a CHANGELOG.md following Keep a Changelog format, documenting all notable changes and features for version history.
• Expanded the README.md with a detailed overview, installation and usage instructions, environment variables, API reference, FastAPI integration examples, and contribution guidelines.

Logging & Observability:

• Enhanced structured logging by integrating asgi-correlation-id for correlation ID propagation, adding a CorrelationIdFilter to log handlers, and updating log formats to include correlation IDs. [1] [2] [3] [4]
• Updated dependencies to require asgi-correlation-id and ensured type hints and logging improvements are reflected in the configuration.

Response & Error Handling:

• Refactored response schemas to use a new RequestMeta model with default factories for correlation ID and timestamp, ensuring every response includes traceable metadata.
• Improved FastAPI request validation error handling to use the correct status code (422 Unprocessable Content) and provide error details in a standardized format.

Testing & CI/CD:

• Added a new GitHub Actions workflow (.github/workflows/tests.yaml) for automated testing and coverage on pull requests, using uv for environment management.
• Created tests/conftest.py with reusable pytest fixtures for environment isolation, temporary directories, and sample configurations, supporting comprehensive and reliable test coverage.
• Updated development dependencies to include pytest-cov and configured coverage to omit test and script files.

Configuration & Dependency Management:

• Improved configuration merging logic in config.py to handle None values gracefully for base paths and module names.
• Upgraded pre-commit hooks and linting tools to latest versions for better code quality enforcement.
• Bumped project version to 0.2.0 to reflect these significant enhancements.

These changes collectively improve Jetpack's reliability, maintainability, and developer experience, setting a strong foundation for future development.

The get_exception_handlers function builds a handlers dictionary but doesn't return it, making it unusable. The function should return the handlers dictionary at the end.
