Task 104: Implement 'scope-up' and 'scope-down' CLI Commands for Dynamic Task Complexity Adjustment (#1069)

* feat(task-104): Complete task 104 - Implement scope-up and scope-down CLI Commands

- Added new CLI commands 'scope-up' and 'scope-down' with comma-separated ID support
- Implemented strength levels (light/regular/heavy) and custom prompt functionality
- Created core complexity adjustment logic with AI integration
- Added MCP tool equivalents for integrated environments
- Comprehensive error handling and task validation
- Full test coverage with TDD approach
- Updated task manager core and UI components

Task 104: Implement 'scope-up' and 'scope-down' CLI Commands for Dynamic Task Complexity Adjustment - Complete implementation with CLI, MCP integration, and testing

* chore: Add changeset for scope-up and scope-down features

- Comprehensive user-facing description with usage examples
- Key features and benefits explanation
- CLI and MCP integration details
- Real-world use cases for agile workflows

* feat(extension): Add scope-up and scope-down to VS Code extension task details

- Added useScopeUpTask and useScopeDownTask hooks in useTaskQueries.ts
- Enhanced AIActionsSection with Task Complexity Adjustment section
- Added strength selection (light/regular/heavy) and custom prompt support
- Integrated scope buttons with proper loading states and error handling
- Uses existing mcpRequest handler for scope_up_task and scope_down_task tools
- Maintains consistent UI patterns with existing AI actions

Extension now supports dynamic task complexity adjustment directly from task details view.
