Server-side A2A dispatch endpoint. Accepts JSONRPC `message/send` or `message/stream`.
No gateway required: the server validates the JWT and enforces authorization itself
(see require_auth/Claims). This handler is the production A2A path.

}Body
Doc-only stand-in for the real request type (nasiko_types::a2a::JsonRpcRequest,
re-exported from the external a2a-lf crate, which has no ToSchema impl and
can't be given one here). Mirrors its actual JSON-RPC 2.0 shape: method is
"message/send" or "message/stream"; params is a SendMessageRequest —
see oss/docs/A2A_PROTOCOL.md for the full parts/metadata schema.
metadata.agent_id selects the dispatch target: absent or "orchestrator"
routes through the routing engine/ReAct orchestrator, anything else proxies
directly to that agent (UUID or name).
Response
A2A event stream (status/artifact updates, completion)
