✨ New Features

New Commands

• tscp - SCP file transfers with Tailscale hostname resolution
• trsync - rsync synchronization with Tailscale hostname resolution
• tmussh - Parallel SSH execution across multiple Tailscale nodes (requires mussh)

• Improved completion - Tab completion for all new commands
• Better error handling - Enhanced argument parsing and validation

Code Quality

• Comprehensive test suite - 5 new test files covering all functionality
• Cross-shell compatibility - Tested on both bash and zsh
• Clean namespacing - Strategic use of prefixes to avoid conflicts

🛠 Technical Changes

  • ts scp file.txt host:/path - Copy files
  • ts rsync -av dir/ host:/path/ - Sync directories
  • ts mussh -h host1 host2 -c "cmd" - Parallel execution

New Files

• tailscale-mussh.sh - Parallel SSH functionality

📝 Usage Examples

# SSH connections
tssh myhost                    # Direct SSH
ts myhost                      # Via dispatcher
tssh user@myhost -p 2222       # With SSH options

# File operations  
tscp file.txt myhost:/tmp/     # Copy files
trsync -av dir/ myhost:/data/  # Sync directories

# Parallel operations
tmussh -h web1 web2 -c "uptime" # Execute on multiple hosts

🔄 Migration

Existing functionality remains compatible:

• ts hostname still works (calls tssh internally)
• All tab completion preserved
• MagicDNS and fallback behavior unchanged
