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).

+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
+```
