"""YAML booleans must not coerce into the scheduler's integer knobs.

`config.yaml` legitimately mixes booleans (`enabled: true`) with integer knobs on
neighbouring lines, so a typo like `scheduler.recursion_limit: true` loads
cleanly — and Pydantic coerces it to `1`, which makes every scheduler-launched
run hit the LangGraph recursion ceiling at its first super-step (the same hole
the app-config guard already closes for Gateway runs). `max_concurrent_runs: true`
serializes the scheduler and `poll_interval_seconds: true` polls five times a
second. Mirrors the app-config boolean guard.
