vpctl 0.7.0

`vpctl manifest init` command to interactively create a new `manifest.yaml` (replaces `vpctl release init` ).

`vpctl manifest validate` command to validate an existing manifest against the embedded CUE schema.

`vpctl manifest schema` command to display the CUE schema and export it for standalone `cue vet` validation.

Manifest validation errors are now more precise: schema constraints, defaults, and cross-field rules are defined in CUE and embedded in the binary. `LoadManifest` now validates manifests automatically during loading.

`authentication.x509` manifest configuration for X509 client certificate authentication.

`logStorage` field on the RustFS infrastructure component to size the log volume PVC independently of data storage.

`configuration.transformations.parallelism` manifest field to control the maximum number of concurrent transformation workflows in Argo Workflows (default: 20).

`exactLength` field in the secret schema to enforce exact value length validation.

`vpctl release init` is deprecated; use `vpctl manifest init` instead.

Breaking: `configuration.licensing` manifest section ( `FlexLM` and `sdkLicenses` ) removed. Parallelism is now controlled by `configuration.transformations.parallelism` .
