## Message

```
Write the user row only when the profile changed

ensureCurrentUser patched the caller's row (updatedAt at least) on every
call. Every query reads that row, so each call re-ran every live query the
user held: about 79 KB of reads with the editor and library open, measured
on a local deployment with dev's data. It runs on each app start and sign-in
event. Skip the write when externalId, display name and avatar are unchanged.
