fix(coding-agent): use shell for external editor on windows closes #1925

packages/coding-agent/CHANGELOG.md

@@ -11,6 +11,7 @@
 - Fixed tmux startup guidance and keyboard setup warnings for modified key handling, including Ghostty `shift+enter=text:\n` remap guidance and tmux `extended-keys-format` detection ([#1872](https://github.com/badlogic/pi-mono/issues/1872))
 - Fixed z.ai context overflow recovery so `model_context_window_exceeded` errors trigger auto-compaction instead of surfacing as unhandled stop reason failures ([#1937](https://github.com/badlogic/pi-mono/issues/1937))
 - Fixed explicit `pi -e <path>` extensions losing command and tool conflicts to discovered extensions by giving CLI-loaded extensions higher precedence ([#1896](https://github.com/badlogic/pi-mono/issues/1896))
+- Fixed Windows external editor launch for `Ctrl+G` and `ctx.ui.editor()` so shell-based commands like `EDITOR="code --wait"` work correctly ([#1925](https://github.com/badlogic/pi-mono/issues/1925))
