Add deploy script, eval refresh script and Go-priced eval data

- scripts/deploy.sh: manual Cloudflare Pages deploy (same steps as CI)
- scripts/refresh-evals.mjs: re-scrape Artificial Analysis + OpenCode Data into evals.js
- evals.js now carries OpenCode Go list prices; Hy4 and LongCat 2.5 left empty
  rather than borrowing a neighbouring model's numbers
- workflow creates the Pages project idempotently
