feat: Optimize all 18 command files using @include reference system

Major streamlining achievement:
- Eliminate 2,733 lines of duplicate content across commands
- Reduce individual command files by ~70% (130-150 → 35-60 lines)
- Leverage existing shared/*.yml reference patterns
- Maintain full Claude Code compliance

Benefits:
• Single source of truth for universal content
• Guaranteed consistency across all commands
• Dramatically reduced maintenance overhead
• Massive token efficiency improvements

Implementation:
- Universal Legend: @include shared/universal-constants.yml#Universal Legend
- Universal Flags: @include shared/flag-inheritance.yml#Universal_Always
- Command patterns: References to appropriate shared/*.yml files
- Template system: Enhanced command-patterns.yml

-## Git Operations
+```bash
+# Standard commit with message
+/git --commit "Add user profile API endpoint"
 
-**Status Operation (--status):**
-- Working tree status and staged changes
-- Current branch and upstream tracking
-- Stashed changes with timestamps
-- Recent commits (last 5) with summaries
-- Unpushed commits count
-- Remote repository status
+# Create PR with reviewers
+/git --pr --reviewers alice,bob --labels api,feature
 
-**Commit Operation (--commit):**
-- Automatic staging of modified files
-- Generate conventional commit message if missing
-- Pre-commit hooks and validation
-- Test verification before commit
-- Create automatic checkpoint
-- GPG signing if configured
+# Interactive cleanup before PR
+/git --history --interactive

-- Switch to existing branch with safety checks
-- Delete merged branches with verification
-- List all branches with descriptions
-- Automatic remote tracking setup
-- Protection for main/master branches
-
-**Sync Operations (--sync):**
-- Fetch from all configured remotes
-- Pull with rebase to maintain clean history
-- Push to tracked remote branch
-- Handle authentication automatically
-- Resolve merge conflicts interactively
-- Update submodules if present
-
-**Merge Operations (--merge):**
-- Fetch target branch before merging
-- Analyze potential conflicts
-- Create checkpoint before merge
-- Use appropriate merge strategy
-- Handle conflicts with interactive resolution
-- Verify merge results
-
-**Stash Management (--stash):**

-- Apply or pop specific stash entries
-- Drop old or unnecessary stashes
-- Handle conflicts during stash application
-
-**History Operations (--history):**

-## Workflow Patterns
-
-**Standard Development Workflow:**
-1. Check status → Understand current state
-2. Create checkpoint → Safety backup
-3. Execute operation → Perform git action
-4. Verify results → Validate changes
-5. Sync with remote → Update shared repository
-
-**Feature Development:**
-1. `git --status` → Check current state
-2. `git --branch feature/new-feature` → Create feature branch
-3. Development work...
-4. `git --commit "Implement feature"` → Commit changes
-5. `git --sync` → Push to remote
-6. `git --merge main` → Integrate with main
-
-**Safe Operations:**
-- Always create checkpoints before risky operations
-- Verify repository state after major changes
-- Use interactive mode for conflict resolution
-- Maintain clean commit history with conventional messages
+# Full feature workflow
+/git --flow feature "payment-integration" --think
+```
 
 ## Deliverables

-## Lifecycle
-Pre_Execution:
-  Risk_Assessment: Calculate risk score 1-10 based on data loss potential, irreversibility, scope, security
-  Environment_Validation: Check required tools, permissions, resources, dependencies
-  State_Preparation: Create checkpoint before risky ops, cache previous results
-During_Execution:
-  Progress_Monitoring: Track operation progress, resource usage, error rates, token consumption
-  Dynamic_Optimization: Adjust parallelism, switch strategies, cache results, fallback to native
-  Error_Handling: Detect errors immediately, classify transient vs permanent, retry/fallback/halt
-Post_Execution:
-  Verification: Confirm expected outcomes achieved, no side effects, state consistent
-  Cleanup: Remove temp files, locks, cached data; update audit logs, metrics, docs
-  Reporting: Generate success/failure report, performance metrics, recommendations
-

-- Branch protection rules
-
-**Team Collaboration:**
