fix: serve .d.cts to CJS consumers

[Luca Schneider (Mad-Kat)]

Fixes a regression in #531: CJS consumers using Node16/NodeNext module resolution can no longer import next-yak and get a TS1479:

error TS1479: The current file is a CommonJS module whose imports will produce 'require' calls; 
however, the referenced file is an ECMAScript module and cannot be imported with 'require'.

Cause

TypeScript matches exports conditions in order, so "types" is selected for every consumer. Before #531, exports had no "types" condition at all and TypeScript fell back to adjacent file matching.

The fix is to use the canonical dual-package pattern.
