Add Gitea PR automation script

- Create automation/gitea-pr.sh for auto-creating PRs via Gitea API
- Update CLAUDE.md with git workflow using the new script
- Deprecate redundant git instructions in PA general-instructions.json
- Token stored securely at ~/.config/gitea-token

Usage: gitea-pr.sh "PR Title" "Description"
