Homebrew LLDB installs but fails its runtime checks

Source: Troubleshooting reference

Symptom: Homebrew successfully pours the lldb bottle, then lldb.sh reports Homebrew LLDB failed its runtime checks after installation.

Root cause: the runtime probe asked LLDB to load /bin/true. Linux provides that path, but macOS provides true at /usr/bin/true, so a healthy macOS LLDB failed the probe before lldb-dap was checked.

Fix: update the dotfiles checkout and rerun:

Terminal window
~/dotfiles/bootstrap.sh upgrade

The probe now loads /bin/sh, which exists on both supported platforms.
