Relaxes the provider policy from 'global config only' to 'global sources':
providers registered by agent-dir (global) extensions are learned once at
daemon startup and allowed on the shared runtime; project-extension
registrations are still rejected with a session warning. Global extensions
load identically for every session, so their providers are daemon-consistent
and cannot leak project state (#76).
- Shim now allows allowlisted ids through and also covers Pi 0.81's native
provider path (registerNativeProvider), closing a bypass.
- Startup learning step loads only global extensions against a scratch cwd
and diffs the runtime's registered provider ids.
- Bumps @earendil-works/* dev/peer ranges to >=0.81.1 <0.82; adapts to the
Agent.streamFn -> streamFunction rename.
- Docs, changeset, unit and acceptance tests updated (global-extension allow
path, late re-registration a la pi-tensorx, native provider rule).
PI WEB only supports globally configured providers (Pi built-ins,
agent-dir models.json, environment credentials). A daemon-wide shim on
the shared ModelRuntime swallows extension registerProvider calls and
makes unregisterProvider a no-op, so one workspace's extensions can no
longer corrupt the provider set of concurrent sessions (issue #76).
Rejections during a services load surface as session warnings through
the existing diagnostics pipeline; late registrations from session
event handlers broadcast a notification to active sessions. Everything
else extensions register keeps working.
Requires manual restart of pi-web-sessiond.service (daemon wiring changed).
