Subject: [PATCH] ci: keep the Supabase project awake (read one row every two
 days)

Free Supabase projects pause after about a week without activity, which would switch off accounts/sync and search by meaning. Public read via the anon key; no secrets.

+# Supabase pauses free projects after about a week without database activity, which would
+# silently switch off accounts/sync and search by meaning. Every two days this reads one
+# row through the public REST API (the anon key only; RLS allows public reads of
+# term_vectors) so the project stays active. No secrets, no checkout, no third-party code.
+# It fails loudly if the backend is unreachable, so a paused project shows up as a red run.
+# Note: GitHub disables scheduled workflows after 60 days without repository activity;
+# re-enable it from the Actions tab if that ever happens.
