* Remote rules -- now Rules can be downloaded from http/https targets like 

https://pkgs.warp.build/toolchains/erlang.js

 -- which makes it possible for us to iterate over them without having to re-release new versions of warp.

* Rule environment variables and PATH are automatically cascading across direct, transitive, and toolchain dependencies -- this means you can now write rules that 

 will be available, and warp will make sure to make it available

* Fix a bug where warp would hang on empty workspaces

* Much faster Label comparison and other performance optimizations
