Add OpenHands to compatibility section

[piyushbag]

Summary

Adds OpenHands to the compatibility section on agents.md now that support for root-level AGENTS.md is documented and implemented in the OpenHands SDK.

Fixes #26

Evidence

When #26 was opened, OpenHands did not document AGENTS.md support. That has since changed:

• Docs: https://docs.openhands.dev/overview/skills describes root-level AGENTS.md as always-on context injected at conversation start.
• SDK: load_project_skills() in OpenHands/software-agent-sdk loads third-party files including AGENTS.md from the git repo root via PATH_TO_THIRD_PARTY_SKILL_NAME and find_third_party_files(). Loaded with trigger=None, so content is always active in the system prompt.

Changes

• components/CompatibilitySection.tsx — add OpenHands entry linking to official skills docs
• public/logos/openhands-light.svg — logo from OpenHands branding assets
• public/logos/openhands-dark.svg — dark-mode variant

Screenshots

How verified

• npx tsc --noEmit — pass
• npm run build — pass
• OpenHands SDK source confirms AGENTS.md is loaded from repo root (case-insensitive filename match)
• Local npm run dev — OpenHands visible in expanded agents grid

Scope notes

• Links to OpenHands skills documentation (not the deprecated all-hands.dev URL from the original issue)
• Does not claim support for @-style file imports or optional spec extensions beyond root AGENTS.md loading

[vercel]

Someone is attempting to deploy a commit to the openai Team on Vercel.

A member of the Team first needs to authorize it.

Quick note on the failing Vercel checks on this fork PR: both Vercel – agents-md and Vercel – agents-md-test are blocked at the GitHub → Vercel authorization step for external contributors (the status links redirect to Vercel team auth). That is expected for fork workflows and is not a code failure on my side.

Could a maintainer re-run/deploy from the PR branch when you have a moment? If the content looks good otherwise, I am happy to adjust formatting or rebase on main.

Closing in favor of #203, which now includes the OpenHands compatibility entry in the same batched branch as the daily-seeded ordering fix (per review on #203).
