feat: Rebrand to gitcaddy-runner with upload helper

- Rename binary from act_runner to gitcaddy-runner
- Update all user-facing strings (Gitea → GitCaddy)
- Add gitcaddy-upload helper with automatic retry for large files
- Add upload helper package (internal/pkg/artifact)
- Update Docker image name to marketally/gitcaddy-runner
