lex-client 0.3.0 record helpers auto-target the account host per call, so the separate header-less account client is unnecessary: one client with the appview proxy service covers queries and writes. Raw com.atproto server/identity/repo calls that must hit the PDS pass service: null explicitly. Hook names unchanged; usePdsClient now marks "must target the account host" call sites and returns a throwing client when logged out. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
