Onboarding type

• New product onboarding (new components.d/<slug>.yml file)
• Other: add a skill to the existing Nsight component and align product grouping.

Summary

• Register Nsight AI Porting Agent as the flat catalog entry nsight-port-cpu-to-gpu.
• Source: NVIDIA/nsight.
• Add the canonical umbrella product Nsight and use it for both Nsight component entries. This intentionally changes Compute Sanitizer's catalog product grouping from Compute Sanitizer to Nsight; its source path and catalog directory remain unchanged.
• Update only that existing generated metadata field so the catalog's byte-stability check stays consistent.

Registration

repo: NVIDIA/nsight
path: skills/nsight-port-cpu-to-gpu/
catalog_dir: nsight-port-cpu-to-gpu

Scope and licensing

This is an existing-component catalog change, not a new component-file onboarding. The source is already public under NVIDIA and declares CC-BY-4.0 AND Apache-2.0. No new license or third-party component is introduced. No skill files, evals, cards, signatures, or generated skill copies are included in this PR; the catalog sync remains responsible for copying the public source.

Validation

• Public source directory and SKILL.md exist on NVIDIA/nsight:main.
• Flat catalog_dir is unique across the component registries.
• YAML and JSON Schema validation passed.
• Upstream source-onboarding checks passed for the porting skill, including the signed payload hashes and benchmark requirements.
• Both Nsight entries resolve to the canonical Nsight product; the existing metadata update changes only product.primary.
• Diff contains only the component YAML, schema enum, and the one-field generated metadata update.

All PRs

• All commits signed off with DCO (git commit -s equivalent sign-off).

Other context

The generated metadata update is included because the metadata CI requires checked-in output to stay byte-stable with the component's declared product. All other existing catalog metadata is unchanged.
