v0.1.14

Summary

• Adds a GitHub Actions workflow that automatically merges main into modal and hetzner deployment branches on every push
• If merge conflicts arise, opens a PR instead so they can be resolved manually
• Uses the existing GitHub App token for authentication

Test plan

• Merge this PR and verify the propagate workflow runs
• Confirm both modal and hetzner branches receive the latest main changes
• Optionally introduce a deliberate conflict on a deployment branch to verify the fallback PR creation works

Closes #169
