feat: initial import of arikigame.com static site

Migrated from tinqs/studio/web/arikigame/ into its own repo
(tinqs/ariki-website, currently under ozan/ for the bootstrap).
Game marketing is no longer hosted in the studio/platform monorepo.

What's in this commit:

- public/  — the live static site (Next.js static export, 39 files
            served by S3 + CloudFront). Last deploy from old location
            was 2026-06-12 (commit 02ccbbf0a in tinqs/studio).
- README.md — self-contained, no longer references the studio tree.
- .gitea/workflows/deploy.yml — same S3 sync + CloudFront invalidation
  pipeline, triggered on push to main when public/** changes. S3 bucket:
  arikigame-com-website, CF distribution: EDMY8TXLTDXLQ.

Verified:
- tinqs clone ozan/ariki-website  (clone ok)
- aws s3 sync public/ s3://arikigame-com-website/  (deploy will run
  on first push to main)
- curl https://arikigame.com  (live content unchanged until first push)

Next steps after this commit lands:
1. Confirm the deploy workflow ran green on tinqs.com → check
   /tinqs/ozan/ariki-website/actions/runs
2. Verify the live site still loads (S3 sync should be a no-op diff since
   the source matches what's already deployed)
3. Transfer ownership: settings → transfer → tinqs org (if you want
   it under tinqs/ariki-website instead of ozan/ariki-website)
4. Remove tinqs/studio/web/arikigame/ + .gitea/workflows/deploy-arikigame.yml
   in a separate studio commit (depends on the deploy here working first)
