Subject: [PATCH] feat: dual-attempt update check with Supabase install ping
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fires a parallel background curl to Supabase during the slow-path
version fetch. Logs upgrade_prompted event only on fresh fetches
(not cached replays) to avoid overcounting. GitHub remains the
primary version source — Supabase ping is fire-and-forget.
