fix(gateway): fall back to the pooler when the derived direct host is unreachable (#1641 )

deriveDirectUrl() swaps the Supabase pooler host to db.<ref>.supabase.co:5432, which is IPv6-only without the paid IPv4 add-on. On IPv4-only networks the direct pool could never connect, and initDirectPool()'s throw killed 'gbrain init --url' and migrations with ENOTFOUND/ECONNREFUSED. getDirectPool() now classifies network-unreachable errors (ENOTFOUND, ECONNREFUSED, ENETUNREACH, EHOSTUNREACH, ETIMEDOUT, CONNECT_TIMEOUT) via the new isNetworkUnreachableError(), self-activates the kill-switch, logs one stderr line pointing at GBRAIN_DIRECT_DATABASE_URL / GBRAIN_DISABLE_DIRECT_POOL, and returns the read pool. Auth/SQL errors still throw (misconfig, not unreachability). The failed pool is ended via endPoolBounded so it can't leak sockets into the now-continuing process. Also surfaces the kill-switch + override envs in the init.ts IPv6 warnings and docs/guides/live-sync.md (they were previously undocumented outside connection-manager.ts).
