Minimal repro for a CIDER issue

How to reproduce:

1. Have Emacs with latest CIDER (tested on 20260518.2116 (1.22.0-snapshot) from melpa)
2. Run npm install then ./node-modules/.bin/shadow-cljs watch
3. M-x cider-connect-cljs, connect to the app build
4. Visit the core.cljs file in a buffer

Expected result: Buffer is connected to the cljs repl Actual result: Buffer displays [not connected] in the status line

Observe that when you comment out the (:require) and (m/def-api) calls in core.cljs, it becomes possible to connect.
