`storage:set` now takes `<name> <property> [<value>]` like every other `:set` command, where omitting the value unsets the property. Previously it took flags and could not distinguish an empty value from an omitted one, so nothing it set could ever be cleared. The flag form keeps working and emits a deprecation warning.
Annotations and labels move to `storage:annotations:set`, `storage:annotations:report`, `storage:labels:set`, and `storage:labels:report`, matching the `scheduler-k3s` equivalents. These operate on a single key, so clearing one leaves the rest in place rather than replacing the whole map as the `--annotation` and `--label` flags do.
Adds plugins/storage/migrate_test.go exercising migrateApp and MigrateLegacyMounts: single deploy phase, cross-phase grouping into one attachment, :ro and free-form volume options preserved on the attachment, idempotency on a second pass, the per-app flag-file fast path that skips already-migrated apps, and the name-collision refusal that aborts before draining. tests/unit/storage.bats gains an end-to-end case that stages a -v line via docker-options:add, runs storage:migrate, and asserts the synthesized colon form shows up in storage:list, the legacy-<hash> entry shows up in storage:list-entries, and the original -v line is gone from docker-options:report on both phases. To make that test (and operators with restored backups) practical, storage gains a storage:migrate <app>|--all subcommand backed by a new MigrateApp helper that skips the per-app flag file so a re-run actually re-scans.
storage:set is the in-place editor for an existing entry; size grows are passed through to a helm upgrade and Kubernetes-incompatible swaps (access-mode, storage-class) are rejected up front. storage:exec spawns a throwaway container that mounts the entry: docker run on docker-local entries, kubectl run with a Pod-spec override on k3s, falling back to bash then sh when no command is supplied. storage:wait blocks until a k3s entry's PVC reports Bound via the storage-status trigger, with a docker-local fast path that just checks the host directory. storage:report --global enumerates every registered entry and the apps that mount it, in text or JSON form.
storage:mount and storage:unmount now accept the named-entry form (--container-dir, --phase, --process-type, --volume-subpath, --volume-readonly, --volume-chown), persisting attachments via the property list. The legacy host:container colon form is preserved for back-compat. Storage now emits its own docker-args-deploy and docker-args-run triggers so docker-local apps continue to receive bind mounts even after their data moves out of docker-options. The install trigger walks every app once per upgrade and converts legacy -v lines into legacy-<hash> entries plus attachments, draining the originals from docker-options last so a partial run leaves the old behavior intact. Lifecycle triggers post-delete, post-app-clone-setup, and post-app-rename-setup keep the attachment store in sync with app state.
Wires the new entry-management commands on top of the Entry type. storage:create accepts both docker-local entries (with idempotent host-directory creation) and k3s entries (which delegate PVC provisioning to a forthcoming scheduler-side storage-create trigger). storage:destroy refuses to remove an entry that any app still mounts. storage:ensure-directory now emits a deprecation warning. storage:mount and storage:unmount keep the existing colon-form behavior so this commit is non-breaking; the named-entry mount form follows in a later commit.
