Function apply_fetch_outcomes 

pub fn apply_fetch_outcomes(
    outcomes: &mut DependencyOutcomes,
    yanked_versions: HashMap<PackageName, (ConcreteVersion, RemovalStatus)>,
    fetch_failed: HashMap<PackageName, FetchFailure>,
    collided_names: HashSet<PackageName>,
    formatter: &dyn EcosystemFormatter,
)

Re-keys a completed fetch’s yanked/fetch-failure findings from raw to normalized package names and applies them to outcomes.

Also records every collided name (two occurrences resolving to different sources, dedup_dependencies_by_source) as not-attempted.

set_fetch_failure_if_absent (not set_fetch_failure) for collided_names: a collided name normalizing to the same key as a genuine failure just recorded above must not clobber it (impl-critic M2).
