1//! `proc kill` - Kill processes
2//!
3//! Examples:
4//!   proc kill node              # Kill all Node.js processes
5//!   proc kill :3000             # Kill what's on port 3000
6//!   proc kill 1234              # Kill specific PID
7//!   proc kill :3000,:8080       # Kill multiple targets
8//!   proc kill :3000,1234,node   # Mixed targets (port + PID + name)
9//!   proc kill node --yes        # Skip confirmation
