Move files that share a delimiter-bounded name prefix within a folder (threshold 2) into a subfolder named after the prefix, dropping the prefix from the filename. Covers plugins/filter (docker, generate, has, merge, get/all), env handler subpackages, utils/roles/entity, utils/tests/swarm/write, role SQL/scripts/templates, keycloak/mailu task-includes, shared tasks/utils/load, and CI scripts. Update every import, query_file/script/include_tasks/src/lookup target, compose bind mount, and python -m path to the new locations. Extend the prefix-grouped-files lint to threshold 2 with dir-level .nocheck and file-head nocheck opt-outs, and skip groups whose shortest member's stem equals the shared prefix. Keep flat only where a loader forbids nesting: WordPress mu-plugins and the docs/requirements namespace. Ansible filter discovery is recursive, so nested filters stay Jinja-resolvable.
