From #1709. Two entries of one framework, like hono-node and hono-bun, are unrelated rows on the board today. This adds variants: same framework, another runtime or documented API. All variants are legitimate and it is separate from mode.

• framework and variant in meta.json. scripts/check_variants.py allows at most two per framework, in its own small workflow.
• Every variant has its row with a pill. A variant is hidden by default: it is listed only with the new Variants filter and has no badges or medals, unless it sets "default_visible": true.
• hono-node and hono-bun are the first two variants.

A hidden variant still counts for the leader of each profile, like a tuned entry that is filtered out. I left out ?variant= for badges: each entry has already its own URL.

Tested with hono-bun hidden: check_badge_parity.js passes and fails without the change in badge_composite, the board in headless Chrome hides and shows the row with the filter, check_variants.py refuses the five wrong cases.

I feel „default_visible“ should be false if not explicitely specified 🤔

Otherwise we will probably see all the variants on top. I would start defensively here - we can change the default later at any time.

Good point, done. default_visible is now false if not specified, and only for variants. hono-node and hono-bun set it to true, so the board stays the same.
