Bump tooling, add check script, remove templates

Upgrade developer toolchain and clean up project files: add a new "check" script (replacing previous lint/fmt), bump TypeScript and add @halo-dev/vite-plugin-halo-theme, update pnpm packageManager version, remove legacy templates HTML files and add "templates" to .gitignore, and apply related changes to vite.config.ts. The lockfile was updated to reflect dependency changes.
