Report #3604

[bug\_fix] Cannot find module '@/components/Button' or its corresponding type declarations.

Add 'baseUrl': '.' to compilerOptions in tsconfig.json, ensuring 'paths' mappings are relative to that baseUrl \(e.g., '@/\*': \['src/\*'\]\).

Journey Context:
You configured path aliases in your bundler to avoid relative imports like '../../../components/Button', and you added 'paths': \{'@/\*': \['src/\*'\]\} to tsconfig.json. Immediately, VS Code underlines the import with TS2307. You restart the TypeScript server and VS Code, but the error persists. You verify the path strings are correct relative to the project root. Searching reveals that TypeScript's path mapping is relative to 'baseUrl', which defaults to the directory containing the tsconfig only if not explicitly set, but often fails to resolve without an explicit anchor. Setting 'baseUrl': '.' explicitly defines the root, allowing the '@/\*' pattern to correctly map to './src/\*'.
