Release v2.0.0 · iconsauce/core

@iconsauce/core 2.0.0

@iconsauce/config is merged into this package, with its full git history.

IconsauceConfig and the Config type are now exported from the @iconsauce/core entry point; the @iconsauce/config package is deprecated
deep imports (@iconsauce/config/lib/*, @iconsauce/core/lib/*) no longer resolve: an exports map restricts the public surface to the package root
requires Node >= 20.19

IconsaucePlugin is re-exported for convenience (canonical home stays @iconsauce/plugin)
package now declares types; toolchain unified on TypeScript nodenext / es2022, ts-jest, Node 24
the test/build integration project no longer depends on postcss-iconsauce
