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.

+Add new `scope-up` and `scope-down` commands for dynamic task complexity adjustment
+
+This release introduces two powerful new commands that allow you to dynamically adjust the complexity of your tasks and subtasks without recreating them from scratch.
+
+**New CLI Commands:**
+- `task-master scope-up` - Increase task complexity (add more detail, requirements, or implementation steps)
+- `task-master scope-down` - Decrease task complexity (simplify, remove unnecessary details, or streamline)
+
+**Key Features:**
+- **Multiple tasks**: Support comma-separated IDs to adjust multiple tasks at once (`--id=5,7,12`)
+- **Strength levels**: Choose adjustment intensity with `--strength=light|regular|heavy` (defaults to regular)
+- **Custom prompts**: Use `--prompt` flag to specify exactly how you want tasks adjusted
+- **MCP integration**: Available as `scope_up_task` and `scope_down_task` tools in Cursor and other MCP environments
+- **Smart context**: AI considers your project context and task dependencies when making adjustments
+
+**Usage Examples:**
+```bash
+# Make a task more detailed
+task-master scope-up --id=5
+
+# Simplify multiple tasks with light touch
+task-master scope-down --id=10,11,12 --strength=light
+
+# Custom adjustment with specific instructions  
+task-master scope-up --id=7 --prompt="Add more error handling and edge cases"
+```
+
+**Why use this?**
+- **Iterative refinement**: Adjust task complexity as your understanding evolves
+- **Project phase adaptation**: Scale tasks up for implementation, down for planning
+- **Team coordination**: Adjust complexity based on team member experience levels
+- **Milestone alignment**: Fine-tune tasks to match project phase requirements
+
+Perfect for agile workflows where task requirements change as you learn more about the problem space.
