"""YAML booleans must not coerce into the subagent and ACP invocation backstops.

`config.yaml` legitimately mixes booleans (`enabled: true`) with integer knobs on
neighbouring lines, so a typo like `subagents.timeout_seconds: true` loads cleanly —
and Pydantic coerces it to `1`. The subagent executor bounds every run with
`future.result(timeout=self.config.timeout_seconds)`, so 1800 seconds becomes a
1-second kill, and `resolve_recursion_limit(self.config.max_turns)` turns a
`max_turns: true` typo into a LangGraph budget of a single super-step. The ACP
agent timeout mirrors `subagents.timeout_seconds` and has the same hole. Mirrors
the app-config, loop-detection, and tool-output boolean guards already in the repo.
