Re-running `storage:mount <app> <entry> --container-dir <path>` against an existing `(entry, container_dir, process_type)` tuple now updates the attachment's mount-time fields in place instead of erroring with `already mounted`. Declarative tooling that wants to change `--volume-options`, `--volume-chown`, `--phase`, `--volume-subpath`, or `--volume-readonly` on an existing mount no longer has to unmount-then-remount, which briefly dropped the volume from `storage:report` and raced against any deploy that fired in the window. The legacy `host:container[:opts]` form keeps its strict `Mount path already exists.` failure.
The `storage:list <app> --format json` payload conflated the
attachment's `Readonly` flag and its `VolumeOptions` field into a
single derived `volume_options` string that rendered as `ro`,
`<options>`, or `ro,<options>` depending on which fields were set on
the underlying attachment. That shape is fine for the legacy
`host:container[:options]` text view but it leaves drift-detection
tooling unable to tell whether a `ro` token came from
`Attachment.Readonly == true` or from the operator setting
`Attachment.VolumeOptions = "ro"` directly. The JSON now exposes
`readonly` (boolean) and `volume_options` (string) as separate
omitempty keys populated straight from the attachment, and
`formatStorageListEntry` combines them at format time for the colon-
form text view. `ParseMountPath` was extended in lockstep so callers
of the legacy `host:container:opts` form no longer have to special-
case the `ro` token themselves.
The named-entry form of `storage:mount` had no way to set the attachment's `volume_options`, even though the legacy `host:container:opts` colon form parses options into the same field and every downstream consumer (the docker-args trigger and the storage:list/storage:report display path) already renders them. Tooling that declaratively re-applies attachments silently dropped options on every re-apply.
storage:list was calling the storage-list plugn trigger which read -v lines from docker-options. After the install-time migration drains those lines into the attachment store, that source is empty for every migrated app and for any app that only ever used storage:create + storage:mount. The fix moves CommandList to call a new in-process ListAppMountEntries helper that reads attachments directly, surfaces the entry name in JSON output via a new entry_name field, and falls back to the entry name as the host token for k3s entries with no host path so the colon form remains well-formed. The storage-list plugn trigger is kept for back-compat with external callers but emits a deprecation warning and now reads from the same attachment-driven source.
Introduces the Entry and Attachment types that the storage plugin will use as the source of truth for named storage volumes, replacing the colon-delimited mount strings stored under docker-options. Entries persist as JSON under config/storage/entries and validate against scheduler-specific rules; attachments persist via the property list and capture how an app uses an entry. The legacy migration name synthesizer is also added so existing colon-form mounts can converge on a deterministic legacy- entry name. Existing storage commands are unchanged in this commit.
