Unify and streamline profile system architecture (#853)

* move claude rules and commands to assets/claude

* update claude profile to copy assets/claude to .claude

* fix formatting

* feat(profiles): Implement unified profile system

- Convert Claude and Codex profiles to use createProfile() factory
- Remove simple vs complex profile distinction in rule transformer
- Unify convertAllRulesToProfileRules() to handle all profiles consistently
- Fix mcpConfigPath construction in base-profile.js for null mcpConfigName
- Update terminology from 'simpleProfiles' to 'assetOnlyProfiles' throughout
- Ensure Claude .claude directory copying works in both CLI and MCP contexts
- All profiles now follow same execution flow with proper lifecycle functions

Changes:
- src/profiles/claude.js: Convert to createProfile() factory pattern
- src/profiles/codex.js: Convert to createProfile() factory pattern
- src/utils/rule-transformer.js: Unified profile handling logic
- src/utils/profiles.js: Remove simple profile categorization
- src/profiles/base-profile.js: Fix mcpConfigPath construction
- scripts/modules/commands.js: Update variable naming
- tests/: Update all tests for unified system and terminology

Fixes Claude profile asset copying issue in MCP context.
All tests passing (617 passed, 11 skipped).

+Validate all task dependencies for issues.
+
+## Dependency Validation
+
+Comprehensive check for dependency problems across the entire project.
+
+## Execution
+
+```bash
+task-master validate-dependencies
+```
+
+## Validation Checks
+
+1. **Circular Dependencies**
+   - A depends on B, B depends on A
+   - Complex circular chains
+   - Self-dependencies
+
+2. **Missing Dependencies**
+   - References to non-existent tasks
+   - Deleted task references
+   - Invalid task IDs
+
+3. **Logical Issues**
+   - Completed tasks depending on pending
+   - Cancelled tasks in dependency chains
+   - Impossible sequences
+
+4. **Complexity Warnings**
+   - Over-complex dependency chains
+   - Too many dependencies per task
+   - Bottleneck tasks
+
+## Smart Analysis
+
+The validation provides:
+- Visual dependency graph
+- Critical path analysis
+- Bottleneck identification
+- Suggested optimizations
+
+## Report Format
+
+```
+Dependency Validation Report
+━━━━━━━━━━━━━━━━━━━━━━━━━━
+✅ No circular dependencies found
+⚠️  2 warnings found:
+   - Task #23 has 7 dependencies (consider breaking down)
+   - Task #45 blocks 5 other tasks (potential bottleneck)
+❌ 1 error found:
+   - Task #67 depends on deleted task #66
+
+Critical Path: #1 → #5 → #23 → #45 → #50 (15 days)
+```
+
+## Actionable Output
+
+For each issue found:
+- Clear description
+- Impact assessment
+- Suggested fix
+- Command to resolve
+
+## Next Steps
+
+After validation:
+- Run `/project:tm/fix-dependencies` to auto-fix
+- Manually adjust problematic dependencies
+- Rerun to verify fixes
