Add enum validation to StorageConfig.Type. A misspelled value currently falls back to bind mounts without any warning.

Thanks for adding this option. In cmd/crossplane/project/run.go, resolveRunOptions selects volume storage only when the value equals "volume" exactly. Any other value, such as "Volume" or "volumes", falls back to bind mounts without an error. A DinD user with a typo gets bind mounts, and the registry then fails in a confusing way. The default error branch in controlplane.go never runs for this input.

Could you add a +kubebuilder:validation:Enum=bindMount;volume marker? Could you also reject unknown non-empty values in resolveRunOptions?

Proposed fix 
 	// The type of storage to use.
 	// Options: "bindMount" (default), "volume".
+	// +kubebuilder:validation:Enum=bindMount;volume
+	// +optional
 	Type string `json:"type,omitempty"`
switch t := c.proj.Spec.Runtime.Registry.Storage.Type; t {
case "", string(docker.StorageTypeBindMount):
	c.storageType = docker.StorageTypeBindMount
case string(docker.StorageTypeVolume):
	c.storageType = docker.StorageTypeVolume
default:
	return errors.Errorf("unsupported registry storage type %q in project file; use %q or %q", t, docker.StorageTypeBindMount, docker.StorageTypeVolume)
}

Add an enum validation marker to StorageConfig.Type permitting only bindMount
and volume. Update resolveRunOptions to preserve the default for empty values
and accept those two values, but return an error for any other non-empty value
instead of falling back to bind mounts.

🔍 Additional research query:

Context7: inspect alecthomas/kong v1.16.1 documentation or source contract for bool flags: whether --internal=falseis accepted for an ordinaryboolfield, and whether--no-internalis generated only when the field usesnegatable:"".

💡 Result:

No relevant context found from external knowledge sources.

🌐 Web query:

github.com/alecthomas/kong v1.16.1 bool flag explicit false --flag=false negatable documentation source

💡 Result:

For **Kong v1.16.1**, the version-pinned test confirms that an explicitly assigned false works: `--flag=false` parses to `false` for a `bool` field tagged `negatable` (with default `true`). It also tests `--no-flag` as the negated form. ([github.com](https://github.com/alecthomas/kong/blob/v1.16.1/kong_test.go))

The v1.16.1 README documents `negatable` as enabling `--no-` to invert the default, but doesn’t mention `--flag=false` specifically; that behavior is established by the version’s test. ([github.com](https://github.com/alecthomas/kong/blob/v1.16.1/README.md))

🌐 Web query:

site:github.com/alecthomas/kong/blob/v1.16.1 ordinary bool field --flag=false Parse bool flag false Kong test

💡 Result:

Yes. In **Kong v1.16.1**, the `TestBoolOverride` test parses `--flag=false` into a `bool` field with a `true` default and expects no error. It also checks that `--flag false` (space-separated) errors. ([github.com](https://github.com/alecthomas/kong/blob/v1.16.1/kong_test.go))

So for a normal bool field, use `--flag=false` to explicitly set it to false.

Preserve an explicit --internal=false override.

Thanks for adding the project runtime default. Could we track whether --internal was supplied and use the project value only when it was absent? When runtime.kind.internal is true, Kong parses --internal=false, but this branch replaces false with true. Run then passes true to WithInternal, so KinD exports internal addresses despite the command override.

Review comment at @cmd/crossplane/project/run.go around lines 162 - 170:
Update runCmd.resolveRunOptions to apply the project runtime’s Internal default
only when the --internal flag was not supplied. Track flag presence separately
from its boolean value so an explicit --internal=false remains false and reaches
WithInternal unchanged.
