[bug\_fix] TS2307: Cannot find module '@/components/Button' or its corresponding type declarations

Configure tsconfig.json paths with baseUrl, then restart TypeScript server in IDE \(Ctrl\+Shift\+P > 'TypeScript: Restart TS Server'\) to clear module resolution cache.

Journey Context:
You just refactored your codebase to use path aliases like \`@/components\` instead of relative \`../../../\` imports. You updated tsconfig.json with \`baseUrl: "."\` and \`paths: \{ "@/\*": \["src/\*"\] \}\`. The CLI build \(\`tsc\` or \`vite build\`\) passes perfectly, but VS Code shows red squiggles under every \`@/\` import with TS2307. You double-check the paths configuration, try adding \`.tsx\` extensions, even consider reverting to relative imports. After an hour of toggling settings, you discover that the TypeScript language server in your IDE cached the old module resolution before you added paths. The fix isn't a code change—it's restarting the TS server to force re-evaluation of the tsconfig.json paths mapping against the filesystem.
