feat: streamline GitHub Actions workflows and improve contributor experience

- Replace complex auto-version.yml with simple PR Docker build workflow
  - Builds Docker images for all PRs using pr-number-sha tagging
  - Removes redundant versioning logic (semantic-release handles this)
  - Adds automatic PR comments with Docker usage instructions

- Optimize test.yml workflow triggers
  - Remove redundant push triggers on main branch
  - Focus on PR testing only for better developer feedback

- Add docker-release.yml for production releases
  - Triggers on GitHub release publication
  - Multi-platform builds (linux/amd64, linux/arm64)
  - Updates release notes with Docker installation instructions

- Add semantic-release.yml workflow for automated versioning
  - Uses conventional commits for version bumping
  - Automatically generates releases and tags
  - Integrates with Docker workflow via release triggers

- Add pre-commit configuration for automatic code quality
  - Includes ruff (with auto-fix), black, isort
  - Provides faster development workflow option

- Enhance contribution documentation
  - Add pre-commit hook option as recommended approach
  - Keep manual script option for comprehensive testing
  - Improve developer workflow guidance

Fixes #215 (automatic changelog generation)
Addresses #110 (Docker builds automation)
References #107 (improved version tracking)

This creates a clean, modern CI/CD pipeline that eliminates redundancy
while addressing multiple community requests around changelog generation,
Docker builds, and release automation.
