Note / 说明

• Connect PLAYWRIGHT_WS_ENDPOINT via the Playwright protocol endpoint with chromium.connect() instead of CDP, and pass remote launch options through launch-options.
• Stop overriding Playwright's browser user agent in Node and Worker contexts.
• Update the Bilibili user video browser fallback to open the user space page before /video, and wait for the JSON arc/search response across that navigation flow.
• Extend the Bilibili browser fallback close timeout and tolerate closed remote pages while handling requestfinished events.

Test plan:

• pnpm vitest run lib/bilibili-video-route.test.ts lib/utils/playwright.mock.test.ts
• pnpm exec oxlint --type-aware lib/utils/playwright.ts lib/utils/playwright.worker.ts lib/utils/playwright.mock.test.ts lib/routes/bilibili/video.ts lib/routes/bilibili/cache.ts lib/bilibili-video-route.test.ts
• pnpm exec oxfmt lib/utils/playwright.ts lib/utils/playwright.worker.ts lib/utils/playwright.mock.test.ts lib/routes/bilibili/video.ts lib/routes/bilibili/cache.ts lib/bilibili-video-route.test.ts --check
• pnpm build:routes
• Attempted live smoke for /bilibili/user/video/646730844?format=json with PLAYWRIGHT_WS_ENDPOINT=wss://cloudflare-patchright.rss3.workers.dev/playwright; repeated checks were blocked by the remote browser endpoint returning 500 or Bilibili returning 412 / risk-control responses.

\n## Auto Review\n- [Rule 21] lib/utils/playwright.ts, lib/utils/playwright.worker.ts: Removed User-Agent configuration for Playwright browsers instead of using RSSHub's built-in `config.trueUA` for requests requiring realistic browser headers. Restore UA settings with `config.trueUA` (e.g., add `--user-agent=${config.trueUA}` to launch args and `userAgent: config.trueUA` to browser context options).
