v0.4.1

Fixes

• Fixed a memory leak in the hub: every server-side Supabase client started a token refresh timer that never stopped and kept the whole request in memory. Long-running hubs grew by hundreds of MB per hour until they ran out of memory. Upgrade recommended.
• Chat: no extra margin above a heading at the top of a message bubble.

Upgrade

• Nothing to do: pull the new images.
