Add NVIDIA DOCA skills component (60 skills for BlueField DPUs / ConnectX NICs)

[tevet-tamir]

Summary

This PR registers the NVIDIA DOCA agent-skills component with the catalog. It adds a single pointer file, components.d/doca.yml, that references the public, OSRB-approved bundle repo NVIDIA-DOCA/doca-skills.

The bundle teaches AI coding agents to use the NVIDIA DOCA SDK on BlueField DPUs and ConnectX NICs — setup, libraries, services, tools, deployment, and debugging.

What this adds

• 60 skills, registered flat (each catalog_dir is a unique doca-* name — no subdirectories), covering DOCA libraries, services, tools, deployment, and cross-cutting setup/version/safety/debug skills.
• One new file only: components.d/doca.yml. No changes to any existing catalog content.

Compliance & readiness

• OSRB: approved (NVBug 6323236).
• Signed: all 60 skills are signed (skill.oms.sig present for every skill).
• Flat layout: every catalog_dir is a flat, lowercase, hyphenated name (no /), matching the catalog convention.
• Collision-checked: validated against the live catalog — no name collisions with existing skills.
• Hygiene: the public bundle passes the reference-hygiene gate (no internal hosts, secrets, or internal-only files; .gitlab-ci.yml / internal pointer dir are not published to the mirror).

Test plan

• components.d/doca.yml paths resolve and each has a SKILL.md in the bundle repo.
• All catalog_dir names are flat and unique.
• No collisions vs the current catalog skill set.
• Bundle repo is public and all skills are signed.
• Catalog daily sync picks up the component and publishes the 60 skills under skills/doca-*.

Reviewed per the catalog onboarding checklist, with source-data verification: all 60 declared paths resolve in NVIDIA-DOCA/doca-skills with complete artifact sets (SKILL.md, skill.oms.sig, skill-card.md, BENCHMARK.md, populated evals/evals.json — verified for every skill via tree sweep, not sampled). BENCHMARK verdicts sampled across flat/libs/services/tools skills: all PASS. All 60 catalog_dirs unique, flat, doca-prefixed; no collisions with the live catalog. Repo public under NVIDIA-DOCA, dual Apache-2.0/CC-BY-4.0 LICENSE, DCO signed, OSRB approved (NVBug 6323236). Author affirmations block added to the body, mapped from the compliance section. LGTM — largest onboarding to date, welcome DOCA!
