fix(perf): handle auth state across iterations, source .env for seed

- Detect scanner_view on launch to handle already-authenticated iterations
  (BaselineProfileRule preserves app data between collection passes)
- Source .env/.env.local for SEED_PHRASE so seed is not passed on CLI
- CLI args still override .env value
