David Laing dd8f51c433 feat: add reverse mode to dependency tree traversal
- Add reverse parameter to GetDependencyTree interface
- Implement reverse SQL traversal (dependents vs dependencies)
- Add comprehensive test for reverse mode (TDD: test-first approach)
- Update existing test calls with reverse=false for backward compatibility

Reverse mode inverts tree direction to show dependents instead of dependencies:
- Normal: JOIN dependencies d ON i.id = d.depends_on_id (traverse UP)
- Reverse: JOIN dependencies d ON i.id = d.issue_id (traverse DOWN)

All storage tests passing. No regressions.
