/**
 * Regression test for #2687 — loadConfig must not emit "unknown config key"
 * warnings for keys that are registered in DYNAMIC_KEY_PATTERNS (e.g. review,
 * model_profile_overrides, claude_md_assembly). These keys were absent from
 * the hand-maintained KNOWN_TOP_LEVEL set in core.cjs, causing false-positive
 * warnings on every read.
 *
 * We trigger loadConfig via `resolve-model` (which calls loadConfig internally)
 * and assert that stderr is EMPTY on success — a typed-IR equivalent of
 * "no warning was emitted" without grepping for specific warning text. The
 * absence of any stderr output IS the contract: loadConfig prints nothing
 * to stderr when every top-level key in config.json is recognized.
 *
 * Migrated from substring `.includes('unknown config key')` text matching
 * to typed empty-stderr assertions per #2974.
