Function inspect_graph_cache 

pub fn inspect_graph_cache(config: &ResolvedConfig) -> GraphCacheStatus

Inspect the persisted module graph the way an analysis run would load it.

Read-only: no analysis, no writes, no network. config.no_cache is ignored for the same reason as in inspect_parse_cache: the question is what state the cache is in, not whether this invocation would consult it.
