CORE v2.0.2

[v2.0.2] - 2026-07-08

🐛 Bug Fixes

• _dispatch_via_a2a(): add Authorization: Bearer <peer_token> header when forwarding
  messages to remote A2A peers. Previously no auth was sent, causing 401 at the peer gateway.
• _dispatch_via_a2a(): use standard SendMessage method (v2.0) instead of legacy message/send.
• _load_peer_config(): resolve token_file path at config load time, store resolved_token
  so _dispatch_via_a2a() can use the correct per-peer credential.

📦 Build

• docker/core-config.yaml: replaced v1.x history-only config with full v2.0 peer routing
  configuration (routing rules + peer registry).
• docker-compose.yml CORE service: mount peer-a-a2a-token.txt secret so the container
  can authenticate to remote peers.
