feat(benchmark): the built-in benchmark, redesigned into the console

The old standalone benchmark.html (Russian-only, Tailwind+Chart.js from CDNs,
never shipped in the crate) becomes a proper sidebar view. Same scoring ideas,
reimplemented: keyword checks with |-synonyms, think-tag stripping, tail-loop
detection, pass/partial/fail — plus what the old page never had: runs go
through the LIVE pipeline (pinned per model, streamed), so every test also
measures tok/s and time-to-first-token with the gateway's real token counts.

A built-in suite of 12 language-neutral probes (math, logic, code, QA,
instruction-following, extraction, translation, JSON formatting); the ⚡ quick
mode runs the 6 short ones — about a minute on a local model. Results: score
bars per model sorted best-first, a per-test grid (click a cell for the full
answer), previous runs and custom tests kept in the browser.

22 new strings in all 7 languages.
