chore: update .gitignore, remove Dockerfile, and enhance documentation

- Added .release-version, CHANGELOG.md, and deploy/docker/docker-bake.override.hcl to .gitignore.
- Removed Dockerfile as part of the cleanup.
- Updated AGENTS.md and README.md to include new documentation on CI/Docker processes and deployment instructions.
- Enhanced package.json with new devDependencies for commit linting and semantic release.
- Updated pnpm-lock.yaml to reflect new dependencies and versions.

These changes streamline the project structure and improve documentation clarity.
