Add TileGym to the NVIDIA Agent Skills catalog

[hannahli-nv]

Onboarding type

• New product onboarding (new components.d/tilegym.yml for NVIDIA/TileGym)

For new product onboarding — author affirmations

By submitting this PR, I confirm on behalf of my team:

• Skills cleared for open source release per NVIDIA's internal IP review process (six-question check, all answers affirmative)
• License selected: Dual (Apache 2.0 + CC-BY 4.0)
• No new license or new third-party component introduced beyond what the source repo already carries
• Source repo is public and under an NVIDIA-owned GitHub org (NVIDIA/TileGym)
• .agents/skills/ path used (TileGym is on the canonical layout; .claude/skills is a symlink → ../.agents/skills)

What this PR adds

components.d/tilegym.yml registering NVIDIA/TileGym for catalog sync under the new components.d schema. TileGym ships 6 skills under .agents/skills/:

• adding-cutile-kernel — guides adding a new cuTile kernel op to TileGym
• converting-cutile-to-julia — port a cuTile Python kernel to Julia
• converting-cutile-to-triton — port a cuTile kernel to Triton
• cutile-python — author and orchestrate cuTile Python kernels
• improve-cutile-kernel-perf — iteratively optimize cuTile kernel performance
• monkey-patch-kernels-to-transformers — integrate TileGym kernels into HuggingFace Transformers

links.discussions: false — TileGym has Issues but no Discussions tab. CONTRIBUTING.md and SECURITY.md are present at default paths.

The commit history of this branch was rebased to the new schema: a merge commit drops the obsolete components.yml/README.md edits (both superseded — components.yml is gone, README.md is now auto-generated), and a follow-up commit adds the single components.d/tilegym.yml entry.

Approve.

Verified end-to-end:

• Source repo NVIDIA/TileGym: public NVIDIA-org, not archived
• LICENSE explicitly dual-licenses .agents/ content as CC-BY-4.0 AND Apache-2.0 (rest of repo is MIT). The .agents/ scope is exactly what syncs into the catalog, so the skill content matches the menu — Dual claim verified at source.
• has_discussions: false upstream → correctly set as links.discussions: false in tilegym.yml
• 6 skill directories upstream match the body's enumerated list
• Single-file PR (components.d/tilegym.yml only) — correct under the post-#40 flow
• Filename slug matches name-derived slug
• All 6 commits DCO signed
• All 5 author affirmations checked

Thanks for patiently rebasing and migrating through the architecture flip.
