fix: simplify and correct branch operation tests

- Remove tests for non-existent cleanupBranch function
- Fix mock setup to match actual setupBranch signature (Octokits not Octokit)
- Update assertions to match actual BranchInfo return type
- Simplify tests to avoid executing actual shell commands
- Add comprehensive test coverage for branch naming and context handling
