* refactor: Simplify Docker workflow to trigger only on tags

- Remove branch-based triggers from docker.yml
- Remove pull request testing job
- Simplify metadata tags to only include semantic versioning
- Update documentation to reflect tag-only builds
- Remove conditional login and push logic since we always push on tags

This ensures Docker images are only built and published for official releases.

* refactor: Integrate Docker builds into release workflow

- Remove separate docker.yml workflow
- Docker images now built as part of the release process
- Add Docker Hub description updates to release workflow
- Simplify CI/CD by having a single release workflow
- Update documentation to reflect integrated approach

This ensures Docker images are only built during official releases
and reduces workflow duplication.

* improve: Enhance Dockerfiles with best practices

Main Dockerfile improvements:
- Copy Cargo.lock for reproducible builds
- Add health check using --version command
- Install curl for health checks
- Better package management

Chat Dockerfile improvements:
- Use npm ci instead of npm install for production builds
- Copy package-lock.json for reproducible builds
- Add proper build arguments for versioning
