SimReady Foundation Release 2026.04.0

What's new since the last release:

Packaging specification — new capabilities (Packaging Core,
Self-Contained, Introspection, Conformance Metadata) with FET_030–033
defining the rules and features for SimReady packages. A sample
packaging toolkit (nv_core/package_sample/) demonstrates creating,
validating, and emitting packages, with reference packages under
sample_content/packaging/.

Documentation — new guides: SimReady Validation Workflow, Getting
Started, SimReady Acceptance Workflow, Features Expansion Workflow,
Profiles Validation Workflow, and Naming Conventions.

Validation of all profiles is now supported via the simready-validate CLI
and the simready.validate Python API. Install from
nv_core/validator_sample/requirements.txt and run against any profile
defined in nv_core/sr_specs/docs/profiles/profiles.toml.
