feat(git-workflow): Add automatic git branch-tag integration

- Implement automatic tag creation when switching to new git branches

- Add branch-tag mapping system for seamless context switching

- Enable auto-switch of task contexts based on current git branch

- Provide isolated task contexts per branch to prevent merge conflicts

- Add configuration support for enabling/disabling git workflow features

- Fix ES module compatibility issues in git-utils module

- Maintain zero migration impact with automatic 'master' tag creation

- Support parallel development with branch-specific task contexts

The git workflow system automatically detects branch changes and creates corresponding empty task tags, enabling developers to maintain separate task contexts for different features/branches while preventing task-related merge conflicts during collaborative development.

Resolves git workflow integration requirements for multi-context development.
