ci: add web frontend lint and type check workflow

[HUQIANTAO]

Add a dedicated GitHub Actions workflow for the Next.js web frontend:

Triggers: Runs on push to main and PRs targeting main, scoped to web/** path changes only.

Steps:

• npm ci with cache (uses web/package-lock.json for cache key)
• ESLint via npm run lint
• TypeScript type checking via tsc --noEmit

Currently there is no CI for the web frontend — TypeScript errors and lint issues can land on main undetected. This workflow catches those at PR time.

Greptile Summary

This PR introduces a GitHub Actions workflow that runs ESLint and TypeScript type checking on the Next.js web/ frontend, scoped to path changes under web/**. The workflow structure is sound — it uses actions/checkout@v4, actions/setup-node@v4 with npm caching, and correct least-privilege permissions — but the TypeScript step has a defect that will cause it to fail on every run.

• The npx tsc --noEmit step runs without first generating next-env.d.ts, which is listed in web/.gitignore and is therefore absent after a clean npm ci. This file is needed to resolve import \"./globals.css\" in web/app/layout.tsx (via /// <reference types=\"next\" />); without it, TypeScript emits TS2307 and exits non-zero.
• The ESLint step (npm run lint) and caching configuration are correct and should work as expected.

Confidence Score: 3/5

The workflow will fail on every run due to a missing type-generation step; merging it as-is adds a permanently broken CI job.

The TypeScript check step is broken out of the box: web/app/layout.tsx imports ./globals.css, and the CSS module type declarations that resolve that import are only loaded via next-env.d.ts, which is gitignored and never generated in this workflow. Every run of the type-check step will exit with TS2307, making the job permanently red. The ESLint step and overall workflow structure are correct.

.github/workflows/web.yml — specifically the TypeScript type check step at the bottom of the job.

Important Files Changed

Filename	Overview
.github/workflows/web.yml	New GitHub Actions workflow for web frontend lint and type-check; TypeScript step will fail on every run because next-env.d.ts (gitignored, required to resolve import "./globals.css") is never generated before tsc --noEmit.

TypeScript check will always fail — next-env.d.ts not generated

web/app/layout.tsx contains import "./globals.css". TypeScript needs a declare module "*.css" ambient declaration to resolve that import, which Next.js normally provides via the /// <reference types="next" /> directive in next-env.d.ts. That file is listed in web/.gitignore, so it won't exist in a fresh checkout after npm ci. With no .d.ts file supplying the CSS module declaration, the type-check step will emit TS2307: Cannot find module './globals.css' or its corresponding type declarations. and exit non-zero on every run.

The most reliable CI fix is to replace the bare npx tsc --noEmit with npm run build -- --no-lint, which generates next-env.d.ts internally before checking types. A lighter alternative is to add a dedicated script to package.json that runs next build --no-lint for CI type checking, or to un-gitignore and commit the small, stable next-env.d.ts file.
