KHI v0.50.0

[kyasbal]

This release features a complete overhaul of the Kubernetes Audit Log parser. This significantly improves the visualization accuracy of resource state changes, specifically enabling more precise tracking of Pod behavior on Nodes and resource deletion flows. It also includes UX improvements for the New Inspection dialog.

🚀 Key Changes

Revamped Kubernetes Audit Log ParserThe Kubernetes Audit Log parsing logic has been completely rewritten, introducing the following enhancements:

• Replaced bind with pod pseudo-subresources under Node resources
  Previously, KHI displayed bind subresources under Node resources to represent scheduling events. This has been replaced with new pod pseudo-subresources. This change allows you to view a detailed timeline directly from the Node's perspective, visualizing not just the scheduling timing, but also when a Pod became Running, when containers terminated, and if errors occurred.
  
• Enhanced Container ID correlation using Pod Status
  The logic for correlating Container IDs in containerd logs with Pods has been improved. In addition to the existing method using container startup logs, KHI now utilizes Container IDs found in the status field of Pod resources within Audit Logs. This enables automatic and accurate correlation of container logs to Pods even if the specific container startup logs are outside the query range, provided the Audit Log contains the Container ID.
• Support for metadata.uid in Control Plane logs
  KHI now generates a resource UID mapping during Audit Log parsing. This allows Control Plane logs that only contain metadata.uid (without resource names) to be correctly mapped to the corresponding resource timeline.
• Strict distinction of Condition statuses
  The visualization of status.conditions now explicitly distinguishes between three states: "Unknown" (explicitly set to Unknown), "Condition does not exist", and "Insufficient log data to determine". This allows users to instantly determine whether the state is due to data loss or an actual Unknown state.

• Visualization of deletion flow considering Finalizers
  KHI now recognizes finalizers in the resource deletion process. When a DELETE request is issued, if finalizers are present, the resource is no longer treated as immediately "Deleted". Instead, it is displayed as "Terminating" until the finalizers are removed.

UI/UX Improvements

• Time-aware cluster name suggestion (Cloud Monitoring Label)
  The cluster name autocomplete behavior in the New Inspection dialog has been changed. The previous method of fetching the "current cluster list" via API has been removed. Instead, KHI now uses Cloud Monitoring labels to suggest only **clusters that actually existed during the input End time and Duration**. This ensures deleted clusters are suggested if they existed during the specified timeframe.

🐛 Bug Fixes* Fixed subresource deletion tracking

Fixed an issue where subresources were not correctly recognized as deleted when their parent resource was deleted.

• Fixed DeleteCollection state restoration
  Fixed an issue where the manifest state was not correctly restored when multiple resources were bulk deleted via DeleteCollection API requests (e.g., during Namespace deletion).
