/**
* Test suite for GitWorkflowOrchestrator
*
* Tests git workflow automation including branch management, commits,
* merges, and PR operations with Conventional Commits support.
*
* Requirements:
* - UC-008: Git Workflow Orchestration
* - NFR-GIT-001: Git operations <5s
* - NFR-GIT-002: Conflict detection accuracy >90%
* - NFR-GIT-003: Commit message generation accuracy >85%
