Sheet Change Slack Notifier.

Watches the A1 ranges you configure and posts to a Slack incoming webhook when an edit lands inside one — saying what changed (cell, old → new, editor). Debounced so a flurry collapses into one message, and HMAC-signed so the receiver can verify it. Installable onEdit (fires for most API writes too).
