refactor(module): drop the native '@/' -> '/src/' alias expansion

Aliasing is resolution policy, and the boundary this branch drew puts
resolution policy on the dev server: Vite applies resolve.alias before a
module is ever served, so a specifier that still carries '@/' when it
reaches the runtime is one the server never rewrote. Guessing '/src/'
natively turned that configuration bug into a silent fallback; now it
fails through the normal not-found path where the import-map miss
logging makes the cause visible.
