fix: resolve critical workflow safety and reliability issues

🛡️ **Critical Security & Reliability Fixes:**

### 🚫 Fixed Force Push Safety Risk
- Added remote HEAD comparison before force pushing
- Aborts workflow if remote main updated by another process
- Prevents concurrent workflow conflicts and data loss
- Enhanced error messages for push failures

### 🤖 Enhanced Claude CLI Reliability
- Removed fallback changelog generation (fails fast instead)
- Added 60s timeout for Claude CLI calls
- Validates Claude CLI availability before proceeding
- Clear error messages when changelog generation fails
- Required dependency: changelog generation must succeed

### 📦 Fixed Version Management Issues
- Replaced npm version with custom Node.js script
- Eliminates package manager inconsistencies
- Proper pnpm lockfile synchronization after version changes
- No more package-lock.json conflicts in pnpm projects

### ⚛️ Atomic Commit Creation
- Single atomic commit instead of multiple amend operations
- Eliminates race conditions from multiple git operations
- All changes (code + version + lockfile) in one commit
- Safer git reset strategy with proper base commit detection

### 🔍 Enhanced Error Handling & Debugging
- Comprehensive error checking at each step
- Debug output for troubleshooting failures
- Graceful cleanup of temporary files
- Clear error messages for common failure scenarios

**Result:** Production-ready workflow that safely handles concurrent operations and fails fast on errors! 🎯
