[bug\_fix] TS2307: Cannot find module '@src/components' or its corresponding type declarations when using tsconfig paths

Add '"baseUrl": "."' to compilerOptions in tsconfig.json. The 'paths' mappings are resolved relative to 'baseUrl', and without it, TypeScript cannot resolve the path aliases.

Journey Context:
Developer sets up path aliases to avoid relative import hell \(e.g., '../../../components'\). They add '"paths": \{ "@src/\*": \["src/\*"\] \}' to tsconfig.json and restart VS Code, but the red squiggly persists on 'import \{ Button \} from '@src/components''. They verify the file exists at src/components/index.ts. They try changing the path to '"@src/\*": \["./src/\*"\]'' but that fails. They search StackOverflow and find conflicting advice about relative vs absolute paths. Eventually, they discover that the 'paths' compiler option is only meaningful when 'baseUrl' is set, as paths are resolved relative to baseUrl. Without baseUrl, TypeScript treats the path mapping as relative to an undefined root, causing resolution to fail silently or fall back to standard node\_modules resolution.
