Creates state processors for write operations in API Platform — the write/Command side of its CQRS-style provider/processor split. Use whenever a POST/PUT/PATCH/DELETE needs custom behavior — persistence logic, soft-delete, file downloads, side effects like emails or events, creating related entities, hashing passwords — or any 'when X is created/updated/deleted, do Y' request, or to understand why a GET processor doesn't fire without write: true (the write vs read phase), even if the user doesn't say 'processor'.
