/**
 * Run the registered fact providers for `ctx`, in dependency order.
 *
 * Providers + fact rules are registered eagerly at `integration.ts` import (the
 * dispatch entry) — including the tree-sitter-backed providers. That's safe for
 * pi-lens's eager graph because the parsing stack loads `web-tree-sitter` (an
 * optional dep) via a dynamic `import()` inside `client.init()`, not at module
 * import, so an unavailable grammar/runtime degrades there rather than crashing
 * the extension at load. As of #402 nothing here uses the `typescript` compiler,
 * so the old lazy-import-with-degrade indirection (#285/#335) is gone.
