What does this change?

Adds og:type=website to leaderboard pages and covers it with a regression test.

Closes #97

How I tested this

• npm run typecheck — passed.
• npm test — 15 files and 379 tests passed. TEMP and TMP pointed to a workspace temp directory because the sandbox's default temp path caused EPERM errors.
• Verified the regression test fails when the metadata line is removed and passes when restored.

Checklist

Thanks @srujankaleru2007, this works. Typecheck and all 379 tests pass on top of develop, and the new test fails with develop's page.ts.
