bug(desktop): "Stale read from <Show>" crash reopening project after full app reinstall + data wipe (macOS)

Description

Desktop app crashes with Error: Stale read from when opening a specific project. Crash persists even after a complete reset: quitting the app, deleting ~/Library/Application Support/ai.opencode.desktop, ~/.local/share/opencode, ~/.cache/opencode, and ~/.config/opencode, fully uninstalling and reinstalling the Desktop app, and reconfirming there is no leftover process (pkill -f opencode before reinstall). The crash still occurs on first attempt to open the project after a totally clean install, and the UI continues to display a stale/previous project name from before a folder rename that happened several sessions ago.
This looks related to #16323, #25131, and #13112, but none of those workarounds (clearing workspace .dat files, killing stray processes) resolved it here, likely because the underlying issue is a genuinely unfixed non-keyed callback pattern rather than local cache state, as noted in #16323
