Chrome processes not released after agent exits on Windows

Bug

On Windows 11, Claude Code (v2.1.158) spawns Chrome processes during agent sessions that are not cleaned up after the agent exits. These orphaned Chrome processes consume significant CPU (~860% across multiple processes) until manually killed.

Environment

• OS: Windows 11
• Claude Code: v2.1.158
• Shell: git-bash (MSYS)

Steps to reproduce

1. Run Claude Code agent sessions on Windows
2. Exit Claude Code
3. Check Task Manager - Chrome processes remain running with high CPU

Expected behavior

Chrome processes spawned by Claude Code should be terminated when the agent session ends.

Actual behavior

Orphaned Chrome processes persist, consuming ~860% CPU. Requires manual Stop-Process -Name chrome -Force to reclaim resources.

Workaround

Manually kill Chrome processes after exiting Claude Code.
