Services Watchdog: HTTPError Handling Fix

Problem

services_watchdog.py was reporting services as DOWN when they returned HTTP 404 on /health. Some services (wavemind) don't have a /health endpoint but ARE alive — they return 404 from a running server, not connection refused.

Fix

Catch urllib.error.HTTPError separately from connection errors. Any HTTP response (200, 404, 500) means the server is alive and listening:

import urllib.request, urllib.error

for name, svc in SERVICES.items():
    try:
        r = urllib.request.urlopen(f"http://localhost:{svc['port']}/health", timeout=5)
        ok += 1  # 200 = alive
    except urllib.error.HTTPError:
        ok += 1  # 404/500 = server is running, just no /health endpoint
    except Exception:
        print(f"[WATCHDOG] {name} DOWN")
        down += 1

Services and their /health behavior

Service	Port	/health	Status
goth-engine	8000	200	Normal
wavemind	8001	404	Expected — no /health endpoint
cline-pass	20131	200	Normal
lobehub (final)	20140	200	{"status":"ok","backend":"lobehub","models":20}
