build: migrate from tsup to tsdown#302
Merged
Conversation
Replace tsup (^7.2.0) with tsdown (^0.20.3) and update build/watch scripts accordingly.
Update exports to use .cjs/.mjs/.d.cts/.d.mts extensions matching tsdown's actual output, and nest type definitions per format to resolve publint errors.

Does it impact the output size? 🤔 |

The output size will be reduced significantly! |

I migrated build tool from tsup to tsdown.
I ran
npx tsdown-migrateaccording to tsdown's Migration Guide.I modified the tsdown configuration to align with the paths defined in package.json.
I added a separate ci-build job running on Node.js 24, since tsdown (Rolldown) requires node:util#styleText which is not available in Node.js 18.
