Function hide_cascade_findings 

pub fn hide_cascade_findings(
    results: &mut AnalysisResults,
    config: &ResolvedConfig,
)

Hide the export and member findings of unused files.

Deleting an unused file removes every unused export, unused type, unused class member and unused enum member in it, so these findings add no information to the report. The pass runs inside the rule pass, so every surface that reports findings hides the same set.

A finding is hidden only when the report lists its file in unused_files, or when an inline fallow-ignore-file unused-file comment suppressed that file. A scope, an issue-type selection without unused files, an ignoreFindings pattern or an off rule that removes the file from the report therefore hides nothing in that file. The issue-type filters clear the suppressed files too, so they must run before this pass. The baseline runs after this pass, so a baseline entry for the unused file does not make its findings visible again. showCascade keeps every finding.
