/**
 * Drop rows for files that were renamed/deleted since the last build.
 *
 * This MUST run unconditionally — even when every remaining file cache-hit
 * (`ctx.allFilesCached`), a file may have been deleted from disk between builds,
 * which produces zero cache misses but still leaves ghost rows in the DB unless
 * the DB's known file set is compared against the current on-disk set. It also
 * MUST run before the derived phases (communities, processes): they re-derive from
 * the DB, so sweeping afterwards leaves them describing symbols that no longer exist.
 *
 * The sweep is confined to the current build's source domain. A narrowed build
 * never looked at files outside its domain, so their absence from the scan says
 * nothing about whether they still exist — deleting those rows is how a code-only
 * refresh used to erase every Document node in the graph.
