gosec G101 matched the identifier fileDropWatchName: its default pattern
includes a bare "pw", which hits case-insensitively inside "fileDropWatch",
and the constant's value then cleared the entropy threshold. Nothing here is
credential-shaped, so rename rather than suppress. Any fileDropW... spelling
keeps the match, hence fileDropReceiverLabel.
overlayWait and the non-iOS overlayWaiter are read only by the iOS overlay
address wait, and the linter analyses the default build only. Suppress with a
reason; the field stays in engine.go as part of the lifecycle.
