• App version check during introduction phase (ErrVersionMismatch).
• HPKE encryption in introduction and handshake.
• Add Channel type in pkg/exchange; encryptedConn abstraction.
• Move store to internal/, expose only pkg/storage.
• Refactor storage API; add query functions.
• fingerprint.Sum (SHA-256); migrate from golang.org/x/crypto/sha3 to stdlib crypto/sha3.
• Protect Conn with mutex; simplify Option type; improve dial/serve/resume error messages.
• KAMUNE_DB_PASSPHRASE and KAMUNE_DB_PATH env vars; getDefaultDBDir().
• Remove dead code (connType, ML-DSA, incomplete Session/Double Ratchet).
• Fix db handle leak on cipher error; fix ECDH private key marshalling.
• Improve error messages and update dependencies.
