Cool stuff. I have a few suggestions though.

(Read: Shadow-cljs as in no Java at all)

This is incorrect, shadow-cljs uses the normal JVM compiler so you definitely need Java.

This shadow-cljs.edn should be enough.

{:dependencies []

 :source-paths ["src/cljs"]

 :builds
 {:extension
  {:target :node-library
   :exports {:activate cljs-ext.core/activate}
   :output-to "extension.js"}}}

• :optimizations defaults to :simple for release and :none for development.
• :output-wrapper is always done for :node-library, the config option has no effect.

If you'd drop lein support you could do this for src/cljs/cljs_ext/core.cljs

(ns cljs-ext.core
  "VSCode extension in ClojureScript"
  (:require ["vscode" :as vscode :refer (commands window)]))
  
(defn say-hello-command []
  (.showInformationMessage window "hello world"))

(defn activate [context]
  (.registerCommand commands "extension.sayHello" say-hello-command)
  (.log js/console "Extension activated."))

The :require syntax is only supported by shadow-cljs (see CLJS-2061 for official progress).

I also recommend npm install --save-dev shadow-cljs in the project so it gets picked over the global install and can be updated with the project.
