Restore and verify --deep now parse the configured age secret key a single time through a new helper that uses age.ParseIdentities and hands every identity to age.Decrypt. A key file with several identities (a whole age-keygen file) is fully accepted, so a blob encrypted to any of its recipients decrypts, not just the first.
The helper is the first step of both commands, so a missing or unparseable key fails before anything is downloaded. Its error names the config source and never echoes the key value. config.extractAgeSecretKey and its silent fallback are removed; the key is stored raw and parsed only where decryption happens. README, the restore help, and the missing-key error now read the key from a file with \$(cat ...) rather than typed literally, keeping it out of shell history.
