/**
 * Reload options that gate project-local, trust-requiring resources — a
 * repository's `.pi/extensions`, project `.pi/settings.json` extension
 * entries, and `.agents/skills` — behind the SDK's project-trust store.
 *
 * Pi Web *executes* project extensions when it builds session services: their
 * factory runs on import and their `session_start` handlers run on startup.
 * Without a trust gate, merely opening an untrusted repository in Pi Web runs
 * repository-controlled code locally (issue #236). The SDK's resource loader
 * only imports project extensions once `resolveProjectTrust` resolves true, so
 * denying trust keeps them dormant.
 *
 * Pi Web and the `pi` CLI share the same trust store. Projects with gated
 * resources default to untrusted until either client records a trust decision.
 * Returns `undefined` when the project has no trust-requiring resources,
 * leaving ordinary projects on their existing load path.
