"""users.google_email — the address Google asserts, kept beside the one the user registered with

Revision ID: 0080_google_email
Revises: 0079_email_canonical
Create Date: 2026-09-04

Since 0079's follow-up a Google sign-in no longer overwrites `users.email`, so a deliberate
`me+siftlode@gmail.com` survives being linked to a Google account whose primary is `me@gmail.com`.
That leaves two true addresses for one account and only one of them stored. This column holds the
other, so the account menu and the Settings sign-in row can show which address Google actually
answers with.

No backfill is possible: Google's answer is only known at sign-in. Accounts linked before this
column existed carry NULL until their owner next signs in with Google — and for the majority the two
addresses are identical anyway, where the UI shows nothing either way.
