Add killIdleDaemonChildren() to clean up SDK-spawned claude processes
that don't terminate after completing their work.
Problem:
- Worker-service daemon spawns Claude SDK processes
- These processes remain alive after work completes
- They accumulate over time, consuming significant memory
- Existing killSystemOrphans() only handles PPID=1 orphans
Solution:
- Add killIdleDaemonChildren() that finds claude processes where:
- Parent PID = daemon's PID (children of worker-service)
- CPU = 0% (idle, not actively working)
- Running > 2 minutes (completed their work)
- Call it from reapOrphanedProcesses() (runs every 5 minutes)
Testing:
- Verified locally: 15+ zombie processes cleaned up
- Memory saved: ~2GB
- Normal processes (MCP server, Chroma) unaffected
