Update omniverse-usd-performance-tuning skill (Usd Optimize rename + cleanup)

[jensjebens]

Onboarding type

• New product onboarding (new components.d/<slug>.yml file)
• Other — content update to an already-onboarded skill. omniverse-usd-performance-tuning was onboarded in Update Omniverse USD performance tuning skill #180; this re-syncs its content. No new components.d/ entry; the existing catalog listing and path are retained.

What changed

Syncs the published omniverse-usd-performance-tuning skill to the current catalog content from the Physical AI Skill Hub (physical-ai-skill-hub-dev main @ 889761b, NVSkills-signed upstream):

• Scene Optimizer → Usd Optimize rename (so-* references → usd-optimize-*); consolidated references/operations/operations.json.
• Refreshed schemas/scripts; skill.oms.sig re-attached over the current content.
• Content cleanup: generalized internal prior-run citations (gb300_03 / SO 110.0.4) and rounded a case-study table's false-precision metrics; third-person description; SKILL.md trimmed under the token budget.
• Regenerated the generated plugins/nvidia-skills catalog copy (build-plugins.py --only nvidia-skills) so it stays byte-identical to canonical — Validate Plugins is green.

Changed paths are confined to skills/omniverse-usd-performance-tuning/ and its generated plugins/nvidia-skills/... mirror (284 files).

IP / license / dependencies

Author affirmation (tick after the internal review):

• Changed content cleared for open source release per NVIDIA's internal IP review process (six-question check, all answers affirmative). Original skill onboarded via Update Omniverse USD performance tuning skill #180; this affirms the content changed in this update (rename + new/edited references).

Verifiable facts on this update (for the OSS Skills PIC reviewer):

• License: unchanged from the published version (no license change in this PR).
• No new third-party component or dependency introduced beyond what the source repo already carries → no new OSRB filing required.
• Path: existing skills/omniverse-usd-performance-tuning/ retained (no path change).
• DCO: all commits signed off.

The six underlying review questions live in NVIDIA's internal onboarding guide (not in this repo); per the PR template, the public PR records only the single affirmation above. Work the questions in your internal attestation, then tick the box.
