fix(windows): detect cursor bundled node process

docs/next/CHANGELOG.md

@@ -3,6 +3,7 @@
 ## Unreleased
 
 ### Fixed
+- Windows panes now keep bare `cursor-agent` launches detected after Cursor hands off to its bundled Node process. (#3032)
 - Claude Code panes now use visible turn, background shell, and background agent activity as working-state fallbacks when OSC titles are unavailable or disabled. (#1630, #2241)
 - Tab bar status commands now remove ESC-prefixed terminal control sequences instead of displaying their sequence bodies as text. (#3001)
 - Unix plugin pane commands now default `PWD` to their resolved working directory, so direct popup tools open at explicit `--cwd` paths while preserving caller-provided `PWD` values. (#2984)
