Detailed Description

A2A server — exposes a NeoGraph as an Agent-to-Agent endpoint.

Speaks the JSON-RPC v0.3 dialect (slash-form method names, kind discriminator) so clients written against either the a2a-js spec or a2a-sdk Python in v0.3 compat mode can connect.

Endpoints:

• GET /.well-known/agent-card.json — AgentCard discovery
• POST / — JSON-RPC dispatcher

Methods:

• message/send — sync round-trip (graph runs, response wrapped as Task)
• message/stream — SSE-framed status updates while graph runs
• tasks/get — recall a Task from the in-memory store
• tasks/cancel — request cancellation (stops further super-steps)

Built on httplib (already a dep) — one OS thread per connection, fine for agent-style traffic where LLM call time dominates.
