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 task permanently from the project.
+
+Arguments: $ARGUMENTS (task ID)
+
+Delete a task and handle all its relationships properly.
+
+## Task Removal
+
+Permanently removes a task while maintaining project integrity.
+
+## Argument Parsing
+
+- "remove task 5"
+- "delete 5"
+- "5" → remove task 5
+- Can include "-y" for auto-confirm
+
+## Execution
+
+```bash
+task-master remove-task --id=<id> [-y]
+```
+
+## Pre-Removal Analysis
+
+1. **Task Details**
+   - Current status
+   - Work completed
+   - Time invested
+   - Associated data
+
+2. **Relationship Check**
+   - Tasks that depend on this
+   - Dependencies this task has
+   - Subtasks that will be removed
+   - Blocking implications
+
+3. **Impact Assessment**
+   ```
+   Task Removal Impact
+   ━━━━━━━━━━━━━━━━━━
+   Task: #5 "Implement authentication" (in-progress)
+   Status: 60% complete (~8 hours work)
+   
+   Will affect:
+   - 3 tasks depend on this (will be blocked)
+   - Has 4 subtasks (will be deleted)
+   - Part of critical path
+   
+   ⚠️  This action cannot be undone
+   ```
+
+## Smart Warnings
+
+- Warn if task is in-progress
+- Show dependent tasks that will be blocked
+- Highlight if part of critical path
+- Note any completed work being lost
+
+## Removal Process
+
+1. Show comprehensive impact
+2. Require confirmation (unless -y)
+3. Update dependent task references
+4. Remove task and subtasks
+5. Clean up orphaned dependencies
+6. Log removal with timestamp
+
+## Alternative Actions
+
+Suggest before deletion:
+- Mark as cancelled instead
+- Convert to documentation
+- Archive task data
+- Transfer work to another task
+
+## Post-Removal
+
+- List affected tasks
+- Show broken dependencies
+- Update project statistics
+- Suggest dependency fixes
+- Recalculate timeline
+
+## Example Flows
+
+```
+/project:tm/remove-task 5
+→ Task #5 is in-progress with 8 hours logged
+→ 3 other tasks depend on this
+→ Suggestion: Mark as cancelled instead?
+Remove anyway? (y/n)
+
+/project:tm/remove-task 5 -y
+→ Removed: Task #5 and 4 subtasks
+→ Updated: 3 task dependencies
+→ Warning: Tasks #7, #8, #9 now have missing dependency
+→ Run /project:tm/fix-dependencies to resolve
+```
+
+## Safety Features
+
+- Confirmation required
+- Impact preview
+- Removal logging
+- Suggest alternatives
+- No cascade delete of dependents
