Cron containers were never reaped once they exceeded their active deadline, so a hung cron task ran indefinitely instead of being retired after 24 hours as documented. `cron:run` now also accepts a `--ttl-seconds` argument, matching the one `dokku run` already takes.

The dynamic `dns-provider-*` properties were reported as `--traefik-dns-provider-<env_var>`, outside the `global`/`computed` namespace every other traefik property uses, so a consumer reading the json report could not tell which of the two a key represented. They are now reported as `--traefik-global-dns-provider-<env_var>`. The `basic-auth-password` property is a credential as well and is now masked in the default report output on the same terms as the dns provider values, meaning the raw value is returned only for `--format json` or when the flag is queried by name.
Kubernetes pulls the app image itself, so a k3s host is free to reap its local copy while the workload keeps running, which the `registry` plugin already does on its own. Deploys, restarts, `dokku run`, and in-cluster cron no longer assert that the image is present locally, falling back to the metadata recorded in the app's current Helm release. A `ps:restart` naming a single process type now rolls only that process type's pods rather than silently redeploying every one. Apps with an `app.json` postdeploy task still require the image locally, as that task runs on the Dokku host.
The preserved copy holds everything the legacy file was not allowed to import, which includes keys that had been `config:unset` on purpose, so a revoked secret can outlive its revocation in a file `dokku config:*` no longer reads. Nothing said the copy was the operator's to remove once reviewed.
Releases 0.38.0 through 0.38.25 recorded the ENV file migration and deliberately left the file at the old path, so 0.38.26 treating a leftover file as a hand-edit replayed the environment as it stood at that upgrade over every `config:set` and `config:unset` made since, reinstating variables and secrets that had been deliberately unset. A file found at the old path once its migration is on record is no longer imported: it is removed when it agrees with the current config, and is otherwise moved aside to `ENV.migrated` with the keys it disagrees on named in a warning. That warning now reaches the operator during an upgrade rather than being swallowed, which is why the overwrite went unreported.
`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.
`storage:create` and `storage:set` accept a `--mode` flag that sets the octal permissions of a docker-local host directory, and `storage:destroy` accepts a `--destroy-host-dir` flag that removes the directory along with its contents. A docker-local entry also honors `--reclaim-policy Delete` at destroy time now, matching how that policy governs a k3s PersistentVolume. Both are limited to the default `/var/lib/dokku/data/storage/<name>` location, the same restriction `--chown` already carries. `storage:set` applies `--chown` and `--mode` to the directory rather than only recording them.
The generated vector config is a snapshot of the app list and their sink properties, but it was only ever written by `logs:set` and `logs:vector-start`. Renaming an app left a source filtering on a label no container carries and gave the new name no source at all, so the app kept a sink with nothing feeding it. Cloning produced the same result for the clone, and destroying an app left its source and sink behind, the latter still pointing at an endpoint decommissioned along with the app. The global relabel transform embeds app names directly in generated VRL, so a rename also left behind a branch naming an app that no longer existed. Every case was silent, and the only repair was an operator running `logs:vector-start`. The `post-app-clone-setup`, `post-app-rename-setup` and `post-delete` triggers now rewrite the config, warning rather than failing so that a config write cannot abort the app operation whose state it is derived from.
Closes#8918.
The alias was only ever used to build the `include_labels` filter on the generated vector source, while dokku labels containers with `com.dokku.app-name` unconditionally. Setting the property therefore pointed the source at a label no container carries, and log collection stopped without any error. The source now always filters the label dokku applies, and a generated remap renames the field on its way to the sink, which is what the property was documented to do. An app whose own alias differs from the global one gets a branch in the global pipeline, so a per-app value is honored even when the app ships through the global sink.
Closes#8916.
