Cam moten f2d825533c Fall back to per-process MCP cleanup on macOS (#37068) ...

## Why

Signaling an MCP server's process group can fail with `EPERM` on macOS,
preventing owned descendants from being terminated.

## What changed

- When a group signal is denied, enumerate the group's processes and signal
  members that still belong to the expected process group.
- Apply the fallback to both `SIGTERM` and `SIGKILL` during MCP stdio server
  cleanup, while retaining the existing group signaling behavior elsewhere.
- Reject invalid process group IDs and avoid signaling processes that have
  moved to another group.

## Testing

Added macOS tests covering cleanup with a live or exited group leader,
`SIGTERM`-resistant descendants, escalation to `SIGKILL`, and unsafe group IDs.
