claude-code over NATS: licence events, a token by request, a login pushed to the manager, MCP servers registered per node or mesh-wide

Events carry what happened and no secret; tokens travel on requests (design 32 §10). The manager's
licence.rotated/switched events make the module ask anthropic-licence-manager.current; at start it
asks once to catch up. A refresh token appearing in the credentials file is a login: it is pushed to
the manager's adopt at once, sealed to the manager's key — the one time a refresh token travels. A
switch replaces the old licence's grant whole, removes the API key and its helper, and rewrites
oauthAccount in ~/.claude.json. New tools register and unregister MCP servers on this node, or with
nodes: all / a list via an mcp.registered event every node consumes; called for one node, the
answer names the other nodes running claude-code. 26 tests.
