Report #14134

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

Configure tsconfig.json with baseUrl set to "." and paths mapping: \`"@/\*": \["src/\*"\]\`. Ensure the wildcard star matches the alias suffix exactly.

Journey Context:
Developer sets up path aliasing in vite.config.ts with \`@\` pointing to \`./src\`. Imports work in the dev server, but TypeScript language server shows red squiggles with TS2307. Developer checks tsconfig.json and realizes paths configuration is missing or incorrectly maps \`"@/\*": \["src/\*"\]\` without the wildcard star, or baseUrl is unset causing relative resolution failure. After adding correct paths mapping and reloading the TypeScript server, errors disappear. The fix works because TypeScript's module resolution algorithm evaluates paths relative to baseUrl before node\_modules lookup.
