fix(module): register _refreshHandler auto-import without .ts extension (#1094)

The auto-import path carried a .ts extension, so Nuxt's codegen wrote a different specifier for dev/prepare vs typecheck. That flip rewrote imports.d.ts and invalidated the vue-tsc incremental cache on every command switch. Strip the extension so every command emits the same path.
