chore: update Docker configuration and CI/CD setup

- Removed Dockerfile and Dockerfile.test as part of the transition to a pre-built image.
- Updated .dockerignore and .gitignore to reflect new build context and ignored files.
- Modified docker-compose.yml to use the new image for the application.
- Enhanced documentation in AGENTS.md and README.md to include CI/CD details and release process.
- Added new dependencies for commit linting and semantic release in package.json and pnpm-lock.yaml.

This commit streamlines the Docker setup and improves the CI/CD workflow with Gitea Actions.
