Supabase Upgrade Migration

Overview

Upgrade @supabase/supabase-js and the Supabase CLI with breaking-change detection, automated code migration, and rollback planning. Covers the v1-to-v2 migration path (auth method renames, data/error destructuring, realtime API overhaul), minor version bumps, @supabase/ssr adoption, and Python SDK upgrades via pip install --upgrade supabase.

Current State
