## Title

    Proposed fix: [Supabase direct connection db.<ref>.supabase.co] 'connect ENETUNREACH <ipv6>:5432' / 'dial tcp [ipv6]: connect: network is unreachable' from IPv4-only platforms (GitHub Actions, Vercel,

## Body

    Recommended action: Use the shared pooler connection string (aws-<n>-<region>.pooler.supabase.com; session mode 5432 for long-lived/migrations, transaction mode 6543 for serverless), or enable the IPv4 add-on. For the Supabase CLI in CI, upgrade (>=1.136.3) and re-run supabase link so it goes via Supavisor.
    
    Option: Switch to the Supavisor shared pooler string [evidence: official_recommended_action]
    Applies when: Any IPv4-only client
    Steps:
    1. Copy the session-mode (5432) or transaction-mode (6543) pooler string from the Connect dialog (user is postgres.<ref>)
    2. Use session mode for migrations/long-lived servers, transaction mode for serverless (disable prepared statements)
    Expected: Connection over IPv4 succeeds
    
    Option: Enable the IPv4 add-on [evidence: official_recommended_action]
    Applies when: Paid plans needing direct connections from IPv4 networks
    Steps:
    1. Enable IPv4 add-on in project settings
    Expected: db.<ref>.supabase.co resolves to IPv4
