ABA 1.4.1 Release Highlights

Mirror lifecycle reliability, stale state detection, and UX improvements.

Docker registry resume — re-running install after a failure now recovers instead of aborting
Stale registry detection — install detects leftover state from a previous unclean uninstall and tells you how to fix it
Registry start shows progress — aba start now shows a live countdown instead of sitting silently (Quay can take up to 10 minutes)
Uninstall cleans up fully — state files and symlinks are removed, no empty leftover directories
TUI progress shows title bar — progress dialogs now display the standard header with host, mode, and version info
aba setup dns crash fixed — no longer crashes on systems with no existing DNS configuration
aba setup ntp wrong network — firewall rule now applied to the correct interface
Single-label domains accepted — domains like lab or local now work in CLI, TUI, and config
oc-mirror for EC builds — engineering candidate builds fall back to stable channel when oc-mirror is not published
Ctrl-C no longer fakes success — interrupted operations correctly report failure
Proxy bootstrap failures fixed — agent IPs and cluster networks now included in no_proxy
Network cross-validation — catches gateway-outside-CIDR, IP collisions, and VIP overlap before install
Security hardening — eval injection guard, temp directory permissions, password masking in logs
