On Windows, `util::process::Child::kill()` only terminated the direct child process, and nothing tied the lifetime of spawned process trees to Zed. External agent servers launched through ACP (e.g. `claude-code-acp` via `npx`) spawn node workers and MCP servers as grandchildren, which were orphaned on every session teardown and accumulated indefinitely — hundreds of idle `node.exe` processes and GBs of RAM over days. This PR assigns spawned processes to a Win32 job object configured with `JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE`: - `kill()` now calls `TerminateJobObject`, killing the entire tree instead of just the (shell wrapper) child. - Dropping `Child` closes the job handle, which makes the OS reap the tree — including when Zed exits for any reason (even crashes), since the OS closes its handles. - Unix behavior (process groups via `killpg`) is unchanged. Added two Windows tests that spawn a real `powershell -> ping` process tree and assert the grandchild is terminated on `kill()` and on drop. Both fail without the fix and pass with it. Verified with `cargo test -p util`, `script/clippy -p util`, and `cargo check -p agent_servers -p dap` on Windows 11. Closes #58873 Release Notes: - Fixed external agent servers and debug adapters leaking helper processes (e.g. node workers and MCP servers) on Windows. --------- Co-authored-by: zed-zippy[bot] <234243425+zed-zippy[bot]@users.noreply.github.com> Co-authored-by: Smit Barmase <heysmitbarmase@gmail.com>
