test: fix stale imports after prompt-async-gate and model-core refactors

- prompt-async-gate.test.ts: refactor ced36bffc removed
  promptAsyncAfterSessionIdle in favor of the unified
  dispatchInternalPrompt({ mode: 'async', ... }). One call site at
  line 1441 was left behind. Replace it with the current API and pass
  the explicit dispatchTimeoutMs so the status-timeout semantics are
  preserved. Also switch the surrounding tests to the third-argument
  timeout form so Bun's typings stay happy.
- runtime-model-readers.test.ts: implementation moved to
  packages/model-core during the layering refactor; the orphaned test
  still pointed at './runtime-model-readers'. Switch to the package
  export via getModelCapabilities and keep the modality-reader
  coverage by deriving keys through the package API.
