createWsClient eagerly invoked a function-form `config.url` to print a dev-time
URL-validation warning. For a module-scope singleton built with
`createVueWsClient({ url: () => useRuntimeConfig().public... })`, that called
useRuntimeConfig() at import time — outside any Nuxt context — and threw
"A composable that requires access to the Nuxt instance was called outside of a
plugin, Nuxt hook, Nuxt middleware, or Vue setup function" (regression vs 0.2.x).
Now only STRING urls are validated eagerly; a function url stays lazy and is
resolved in _getUrl() at connect time (as in 0.2.x). Bump 0.3.1.
- 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.
