fix(ci): migrate GitHub Actions workflow from Deno to Node.js

The project was migrated to Node.js + HonoX + Vite SSG in 9194a0c,
but the CI workflow still used Deno commands (deno fmt, deno task),
causing build failures. This updates the workflow to use npm commands
and applies deno fmt formatting rules that were enforced by CI.

Changes:
- Remove denoland/setup-deno action
- Replace deno commands with npm ci and npm run build
- Add npm cache to speed up CI
- Apply deno fmt to fix formatting violations

Fixes the CI failure in commit b414bfe.
