v0.1.2

The name has been updated, but the function remains unchanged.

v0.1.1

Added life_test.go file.

v0.1.0

This version introduces a minimal goroutine lifecycle controller
focused on correct shutdown ordering and WaitGroup safety.

• Rejects new goroutines after shutdown begins
• Provides a shared root context for cooperative cancellation
• Guarantees that WaitGroup.Add is never called concurrently with Wait

This release makes no guarantees about goroutine termination or
resource cleanup. Those responsibilities remain with the goroutines
themselves.
