mcp_io_opcua 0.2.1

OPC UA Binary adapter (MVP) for mcp_io. Hello/Ack transport codec + OpcUaSession abstraction.

0.2.1 - 2026-05-23 - mcp_bundle 0.4.0 cascade

Changed (cascade)

• mcp_bundle caret bumped from ^0.3.0 to ^0.4.0.
• mcp_io caret bumped from ^0.2.0 to ^0.2.1.

mcp_io_opcua does not touch UiSection.pages directly — caret-only cascade. Consumers should bump to ^0.2.1.

• Security policies — Basic256Sha256, Aes128_Sha256_RsaOaep, Aes256_Sha256_RsaPss.
• WebSocket byte transport (opc.ws:// / opc.wss://).
