 * quick-batch-command-router.test.cjs — Behavioral tests for the
 * `msd-tools quick-batch` command router (#3676, Phase 4 of epic #3344 /
 * ADR-1239 "Quick-batch binding").
 *
 * Module: msd-core/bin/lib/quick-batch-command-router.cjs
 *   (compiled from src/quick-batch-command-router.cts)
 *
 * Follows `tests/roadmap-command-router.test.cjs`'s pattern: unit-level
 * tests inject `_quickBatch`/`_quickBatchDispatch` mocks (same `_`-prefix
 * seam convention `graphify-command-router.cts` established) and assert on
 * recorded call shapes; a smaller set of end-to-end tests drive the REAL
 * compiled router through `msd-tools quick-batch <verb>` via `runMsdTools`
 * to prove the `HOST_COMMAND_ROUTERS` wiring itself (test-matrix rows 46-47).
