feat(agent): add automated branch and PR creation

Added createBranch and createPR options to the agent API endpoint, enabling automatic branch creation and pull request generation after successful agent task completion. Branch names are auto-generated from the agent message, and PR titles/descriptions are auto-generated from commit messages. This streamlines CI/CD workflows by eliminating manual Git operations after agent runs.
