/**
 * Muse Code runtime profile.
 *
 * Everything the chip needs is in `~/.config/muse/settings.json`, a flat JSON document — no pane
 * scraping, no catalog fetch. Verified content (muse 0.1.0-R708.1):
 *   {"schema_version":1,"provider":"meta","model":"muse-spark-1.2-contributor"}
 * `reasoning_effort` is absent until the user changes it; muse's own `--help` documents the default
 * as `high`, so an absent key is reported as that rather than as "unknown".
