fix: reduce excessive reconciliation and disable dev mode logging

[ziyang-lin-404]

Summary

• Remove hardcoded Development: true from zap.Options for production-appropriate logging
• Add status change detection to ScalityUIComponentExposer to avoid unnecessary API calls
• Add GenerationChangedPredicate for ScalityUI watch to prevent unnecessary reconcile triggers

Problem

1. Verbose debug logs in production: The Kubebuilder scaffold sets Development: true by default, causing verbose debug logs in production environments.

2. Unnecessary status updates: ScalityUIComponentExposer was calling Status().Update() on every reconcile, even when status hadn't changed, causing:

   • Extra API Server load
   • Unnecessary etcd writes
   • Potential cascade of watch events

3. Unnecessary reconcile triggers: ScalityUI status changes were triggering ScalityUIComponentExposer reconciliation, even though Exposer only depends on ScalityUI.Spec.Networks.

Changes

1. cmd/main.go

// Before
opts := zap.Options{
    Development: true,
}

// After
opts := zap.Options{}

2. reconcile_context.go

• Added oldStatus field to store original status
• Added SetOldStatus() and GetOldStatus() methods
• Added ExtendedState interface

3. controller.go

• Save oldStatus after fetching CR: currentState.SetOldStatus(cr.Status.DeepCopy())
• Added GenerationChangedPredicate to ScalityUI watch

4. status.go

• updateStatus() now compares oldStatus with current status before calling API
• Added conditionsEqual() function to compare conditions (ignoring LastTransitionTime)

How to enable debug logging

# Development mode (console format + debug level + stacktraces)
./manager --zap-devel

# Or just adjust log level
./manager --zap-log-level=debug

# In Kubernetes deployment
spec:
  containers:
  - name: manager
    args:
    - --zap-devel
