fix: pre-filter all default exclude patterns in batch organizer findFiles

Previously only node_modules was pre-filtered at the findFiles level.
Now all default excludes (node_modules, dist, build, out, .git, coverage)
are pre-filtered via brace expansion glob to avoid enumerating thousands
of files in build artifacts and dependencies.
