ktop Release v0.6.2

This release adds container-level CFS CPU throttling visibility and an at-a-glance Cluster Health Score percentage in the overview header.

Features

• CFS CPU Throttling (#167):
  • Added container_cpu_cfs_throttled_seconds_total, container_cpu_cfs_throttled_periods_total, and container_cpu_cfs_periods_total to the Prometheus metric allowlist.
  • Computed per-container and pod-level CFS CPU throttling percentages (preferring throttled/total period ratios with a throttled-seconds rate fallback).
  • Added a sortable THROTTLE column (key h) to the Overview Pods table (toggleable via the C column selector and persisted in ~/.ktop/config.yaml) and the Pod Detail Containers table, plus a CFS: indicator in the Pod Detail Info header.
• Cluster Health Score (#170):
  • Added a composite 0–100 cluster health score calculated from node readiness, failed/OOM pods, PSI saturation stalls (>20%), node pressure conditions, and metrics availability.
  • Rendered color-coded Health: <score>% in the Cluster Summary header (green ≥90%, yellow ≥70%, orange ≥50%, red <50%).
