fix(plugins): resolve line-38 conflict with docs#48

docs#48 (merges first) changes line 38 to a cross-platform MCP
description. This commit synthesises both: keeps docs#48's framing
("works with any MCP-compatible agent") but adds docs#54's Hermes
integration detail (container startup, A2A tool provider, list_peers /
delegate_task / send_message_to_user) and keeps docs#48's reference
to the MCP Server guide.
