v1.5.0-rc.2

Second release candidate — bug fixes, security hardening, and new UI features on top of RC1.

What's new since RC1

Up-to-date & pinned badges — Containers table Kind column now shows a green check for up-to-date containers and a pin icon for skipped/pinned updates

Mobile UI fixes — DataTable icon clipping, version column alignment, responsive grid margins, vertical scroll on containers page
Competitor comparison page accuracy — Corrected claims for WUD, Watchtower, Portainer, Dockhand based on research
Container store performance — SHA-256 hash caching for security state comparisons
Stats collector refactor — Interval-based deleted state sweep instead of inline on every call
WebSocket hardening — Extracted rate-limit key resolution, buffer overflow handling in log streams
CI pipeline stability — Fixed auto-tag pre-release crash, Scorecard alerts, load test thresholds, Playwright artifact naming
