Zshy TypeScript Library Build Tool

Zshy (pronounced "zee-shy") is a bundler-free build tool specifically designed for TypeScript libraries, leveraging `tsc` for core transpilation. It aims to simplify the build process by requiring no separate configuration file, instead inferring settings from `package.json` and `tsconfig.json`. Key features include declarative entrypoint mapping within `package.json#/zshy`, automatic generation of `"exports"` and `"jsr.json"` fields, and native support for dual-module builds (ESM and CJS) from a single TypeScript source. It currently stands at version 0.7.0, with an active development pace indicated by frequent releases, and differentiates itself by its `tsc`-powered, no-bundler, no-config philosophy, making it an ideal choice for straightforward TypeScript library projects needing robust dual-package support without the complexity of traditional bundlers.
