func NewTicker ¶

func NewTicker(ctx context.Context, interval time.Duration) <-chan struct{}

NewTicker returns a channel that emits ticks starting immediately and then roughly every `interval` thereafter.

Design goals:

• Single goroutine, single time.Timer (no busy waits, no extra deps).
• Coalescing semantics: if the consumer is slow, ticks do NOT accumulate. The channel is buffered with size 1; sending is non-blocking.
• Monotonic scheduling: next tick time is advanced by fixed `interval` from the *ideal* schedule (next += interval), preserving cadence and avoiding bursts if we ever fall behind.
• Cancellation via ctx.Done().
• If interval <= 0, falls back to 1s.

First tick is sent immediately (best for “kick off then repeat” workflows).
