- ServiceChecker now runs as a background timer task (30s), skips overlapping runs, and caches per-endpoint state from Preferences (services + kubernetes). Legacy UI flags are kept in sync for StatusView/Overlay.
- Auto-reload on Preferences save: ServiceChecker listens to Config.didChange, clears caches, invalidates freshness, and triggers an immediate refresh.
- Preferences: ensure in-progress text edits are committed before saving (endEditing) for Kubernetes, Services, and Ports tabs.
- PortForwardManager: fix crash in termination handler by reading terminationStatus from the provided Process instance, then updating state on the manager queue.
- Minor: keep existing UI wiring; logging intact for diagnostics.
TODO: remove (list unused code paths)
- Config.primaryKube (unused in prole-app)
- Config.string(_:, default:) (unused in prole-app)
- Config.int(_:, default:) (unused in prole-app)
- PortForwardManager.parsePFCommand tuple parts `modeBackground` and `keepAlive` (never read by callers)
- Config.pfModeBackground and Config.pfKeepAlive (currently ineffective because their values aren’t used downstream)
