* feat: add task master (tm) custom slash commands

Add comprehensive task management system integration via custom slash commands.
Includes commands for:
- Project initialization and setup
- Task parsing from PRD documents
- Task creation, update, and removal
- Subtask management
- Dependency tracking and validation
- Complexity analysis and task expansion
- Project status and reporting

+Add a dependency between tasks.
+
+Arguments: $ARGUMENTS
+
+Parse the task IDs to establish dependency relationship.
+
+## Adding Dependencies
+
+Creates a dependency where one task must be completed before another can start.
+
+## Argument Parsing
+
+Parse natural language or IDs:
+- "make 5 depend on 3" → task 5 depends on task 3
+- "5 needs 3" → task 5 depends on task 3
+- "5 3" → task 5 depends on task 3
+- "5 after 3" → task 5 depends on task 3
+
+## Execution
+
+```bash
+task-master add-dependency --id=<task-id> --depends-on=<dependency-id>
+```
+
+## Validation
+
+Before adding:
+1. **Verify both tasks exist**
+2. **Check for circular dependencies**
+3. **Ensure dependency makes logical sense**
+4. **Warn if creating complex chains**
+
+## Smart Features
+
+- Detect if dependency already exists
+- Suggest related dependencies
+- Show impact on task flow
+- Update task priorities if needed
+
+## Post-Addition
+
+After adding dependency:
+1. Show updated dependency graph
+2. Identify any newly blocked tasks
+3. Suggest task order changes
+4. Update project timeline
+
+## Example Flows
+
+```
+/project:tm/add-dependency 5 needs 3
+→ Task #5 now depends on Task #3
+→ Task #5 is now blocked until #3 completes
+→ Suggested: Also consider if #5 needs #4
+```
