OS process leaked on timeout in BackendHealthMonitor

[fatihkan]

Bug Description

In BackendHealthMonitor.swift:193-218, when a health check times out, the spawned Process is not terminated. The zombie process continues running indefinitely, leaking system resources.

Location

CreedFlow/Sources/CreedFlow/Services/Health/BackendHealthMonitor.swift:193-218

Severity

Critical — OS process leak. Over time, accumulates zombie processes.

Steps to Fix

1. Store a reference to the Process
2. On timeout, call process.terminate() and process.waitUntilExit()
3. Register with ProcessTracker for cleanup on app exit
