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).

+Remove a dependency between tasks.
+
+Arguments: $ARGUMENTS
+
+Parse the task IDs to remove dependency relationship.
+
+## Removing Dependencies
+
+Removes a dependency relationship, potentially unblocking tasks.
+
+## Argument Parsing
+
+Parse natural language or IDs:
+- "remove dependency between 5 and 3"
+- "5 no longer needs 3"
+- "unblock 5 from 3"
+- "5 3" → remove dependency of 5 on 3
+
+## Execution
+
+```bash
+task-master remove-dependency --id=<task-id> --depends-on=<dependency-id>
+```
+
+## Pre-Removal Checks
+
+1. **Verify dependency exists**
+2. **Check impact on task flow**
+3. **Warn if it breaks logical sequence**
+4. **Show what will be unblocked**
+
+## Smart Analysis
+
+Before removing:
+- Show why dependency might have existed
+- Check if removal makes tasks executable
+- Verify no critical path disruption
+- Suggest alternative dependencies
+
+## Post-Removal
+
+After removing:
+1. Show updated task status
+2. List newly unblocked tasks
+3. Update project timeline
+4. Suggest next actions
+
+## Safety Features
+
+- Confirm if removing critical dependency
+- Show tasks that become immediately actionable
+- Warn about potential issues
+- Keep removal history
+
+## Example
+
+```
+/project:tm/remove-dependency 5 from 3
+→ Removed: Task #5 no longer depends on #3
+→ Task #5 is now UNBLOCKED and ready to start
+→ Warning: Consider if #5 still needs #2 completed first
+```
