Module explicit_transfer_crypto 

Encrypted explicit file-transfer helpers shared by native hosts.

Iroh bi-stream wire format:

• each logical write is one length-framed ORTCE1 envelope (RAW_STREAM_TYPE_ID = 3)
• the first decrypted frame is the 0x02 protocol byte
• the second decrypted frame is 4-byte JSON length || header JSON
• subsequent decrypted frames are file chunks

The 0x02 byte remains the explicit-file stream discriminator; current transport uses the admitted logical-Iroh stream rather than a direct WebRTC route.
