- AGENTS.md: canonical client reference — factories + the app `ws` singleton, send()
(streaming via the 4th progress arg, no-timeout caveat), listen/listenWhileMounted,
the EventTarget mechanics, the setAppReady() gate, the SSR pattern, and a footgun checklist.
- package.json: add AGENTS.md to files[] so it ships to node_modules in consumer installs.
- README: correct the ApiClient method table — `bearerToken` getter / getBackendUrl() /
setBearer(null) (getBearer/getServerUrl/clearBearer never existed) + accurate verb signatures.
