New artisan command brain:clean {--chunk=100} {--dry-run} that dispatches
the DeleteFromIndex job for soft-deleted BrainMemory rows (those in
onlyTrashed scope). Cleans up orphaned Qdrant + Elasticsearch index
entries that remain after a memory is soft-deleted.
--dry-run counts without dispatching.
php/tests/Feature/Console/BrainCleanCommandTest.php covers Good
(dispatches on trashed), Bad (invalid chunk), Ugly (--dry-run prevents
dispatch).
