Mailglass.SuppressionStore.Ecto (Mailglass v0.1.0)

Default Ecto-backed Mailglass.SuppressionStore implementation.

check/2 performs the union lookup from CONTEXT.md §specifics:

SELECT 1 FROM mailglass_suppressions
WHERE tenant_id = $tenant_id
  AND (
    (scope = 'address' AND address = $recipient) OR
    (scope = 'domain' AND address = $recipient_domain) OR
    (scope = 'address_stream' AND address = $recipient AND stream = $stream)
  )
  AND (expires_at IS NULL OR expires_at > now())
LIMIT 1

The UNIQUE index on (tenant_id, address, scope, COALESCE(stream, '')) plus the secondary (tenant_id, address) index serve the OR-union efficiently (Postgres chooses per-branch plans).

record/2 uses on_conflict: {:replace, [...]} to make admin re-adds idempotent.
