The bash :report implementation for the scheduler-docker-local plugin is replaced with a compiled golang binary. The plugin already shipped golang code, so the report subcommand is added alongside its existing triggers binary, and the init-process and parallel-schedule-count helpers remain in bash for the deploy pipeline.

Emitting the restart policy as a `--restart` argument from a `docker-args-process-deploy` trigger exposed a latent gluing bug: proxy and builder triggers concatenated `$STDIN$output` with no separator, and the scheduler and builders appended `docker-args-process-*` output directly onto the older `docker-args-*` output, so adjacent arguments could merge into values like `--restart=on-failure:10--label`. A space is now inserted at both the trigger echo and the concatenation so arguments always stay separated.

The `<plugin>-global-<property>` keys in `:report` output returned the resolved value with the built-in default substituted in, so external tooling could not distinguish a property that had been set globally to the default from one that had never been set. The bare keys for caddy, haproxy, and traefik global-only properties had the same shape. The `global-<property>` keys now hold the raw stored value and are empty when nothing has been set, and a new `computed-<property>` key holds the effective value used at runtime, falling back through the per-app value (where one exists), the global value, and the built-in default. The bare global-only keys for the three proxy plugins are removed in favor of the raw/computed pair. Closes#8631.

The bare `init-process` and `parallel-schedule-count` keys previously returned the computed value, so external tooling could not tell whether a property had been set on the app or was merely defaulting. Both properties are now also configurable with `--global`, the report exposes `computed-*` and `global-*` keys alongside the bare raw keys, and the deploy path honors the global value before falling back to the linuxserver.io vendor heuristic.
The `value_exists` variable in the report info-flag loop is no longer read after the `not deployed` failure was removed, and was already unused in domains, haproxy-vhosts, traefik-vhosts, caddy-vhosts, and openresty-vhosts. Drop the declaration and the trailing assignment so the loop reads cleanly across all plugins.
Several plugin `:report` subcommands erroneously failed with `not deployed` when an info-flag matched a property that was empty. Empty values are legitimate for configuration properties pre-deploy and the `--format json` path already returns them without error. Remove the `value_exists` check across nginx, checks, git, certs, scheduler-docker-local, and the builder-* plugins so the info-flag form behaves consistently with the JSON form.
The argument-handling block in each plugin's report command overwrote APP with --global before checking whether $1 actually held an info flag, so `dokku <plugin>:report --global --<plugin>-foo` always emitted the full report instead of the requested value. Reorder the conditionals across the sixteen plugins that share the pattern so the info-flag check runs first, and add a regression bats case for each one.

### Other
- #8498: @josegonzalez Migrate environment variables to plugin properties
CallExecCommand wraps non-zero exit codes as errors with the code populated on the response, so storage:exec was returning the wrapped error and being collapsed to exit 1 by LogFailWithError before the os.Exit branch ran. Both storage's CommandExec and scheduler-docker-local's TriggerSchedulerStorageExec now check ExitCode before err so the underlying tool's status flows through verbatim. Separately, the legacy host:container colon form of storage:mount used to write straight into docker-options, but storage:list now reads only attachments, so newly mounted legacy-form storage was invisible. CommandMount and CommandUnmount route the colon form through LegacyMountToEntry plus AddAttachment / RemoveAttachment, making storage:list show every mount regardless of form while preserving the existing "Mount path already exists." / "Mount path does not exist." error wording.
Moves the actual exec out of the storage plugin and into a new scheduler-storage-exec plugn trigger. scheduler-docker-local does docker run with TTY-aware -it/-i selection and --user derived from entry.Chown; scheduler-k3s creates a throwaway Pod via the kubernetes API, waits for it to reach Running with structured error reporting (ImagePullBackOff and friends are surfaced from the container status verbatim, no kubectl involvement), execs the user command via the existing SPDY plumbing in k8s.go, and deletes the Pod on the way out. (Entry).Validate now accepts either an absolute path or a docker named-volume token for docker-local entries so the migration synthesizer's named-volume legacy entries work cleanly. storage:exec gains --as-user for one-off uid overrides, propagates the underlying tool's exit code via os.Exit, and detects TTY/interactive mode from os.Stdin so non-interactive scripted use no longer trips over docker's input-device-is-not-a-tty error.
Every `:report` subcommand now recognizes `--global` as a scope selector that limits the report to globally-configured properties, including in JSON form via `--global --format json`. Previously this combination was rejected because `--global` was treated as an info flag, conflicting with `--format`. The shared `common.ParseReportArgs` helper now returns a `ReportArgs` struct exposing the parsed scope; each Go and bash report selects a global-only flag map when scope is global, and skips per-app verification.
The scheduler-run script classified CNB-based images as `herokuish` because
`is_image_herokuish_based` returns true for them, which caused the
`docker-args-process-run` trigger for builder-pack to skip injecting
`--entrypoint launcher`. Without that flag the container fell back to the
image entrypoint (`/cnb/process/web`) and dropped the user-supplied
arguments. Mirror the deploy-side detection so CNB images set
`IMAGE_SOURCE_TYPE=pack`, allowing the launcher entrypoint to be added.
When ps:rebuild runs against an image-based deploy via git:from-image, the resulting image often shares the same SHA as the previous deployment, so retiring the old container's image would target the live image of the new container. The retirement is now skipped when another running container of the same app still references the image, and the cron retire loop self-heals previously stuck entries the next time it encounters them.
The docker-local scheduler now sends `SIGTERM` to old containers immediately after a successful deploy via `docker container kill --signal=SIGTERM`, rather than waiting `wait-to-retire` seconds before signaling. This matches Heroku's graceful-shutdown contract and lets applications begin draining in-flight work as soon as proxy traffic switches. The existing `wait-to-retire` grace period and `stop-timeout-seconds` hard-stop continue to apply unchanged as the authoritative cleanup path.
When scaling a process type to a smaller count, the indices above the
new count had their `CONTAINER.<proctype>.<idx>` state files deleted but
the underlying Docker containers were never registered for retirement,
so they remained running indefinitely. The cleanup block now reads each
orphaned state file and registers its container id with the existing
`scheduler-register-retired` trigger before the file is removed.
