// I/O dependencies for query(). Passing a `deps` override into QueryParams
// lets tests inject fakes directly instead of spyOn-per-module — the most
// common mocks (callModel, autocompact) are each spied in 6-8 test files
// today with module-import-and-spy boilerplate.
//
// Using `typeof fn` keeps signatures in sync with the real implementations
// automatically. This file imports the real functions for both typing and
// the production factory — tests that import this file for typing are
// already importing query.ts (which imports everything), so there's no
// new module-graph cost.
//
// Scope is intentionally narrow (4 deps) to prove the pattern. Followup
// PRs can add runTools, handleStopHooks, logEvent, queue ops, etc.
