YU AI Manager v4.255.15

YU AI Manager v4.255.15

AI-generated image metadata management WebUI — on-device, no cloud required.

What's new since v4.255.9

• Headroom dashboard (/headroom) — Integrates headroom proxy stats into yu: version, uptime, token savings rate, request statistics, per-model breakdown, compression executor state with 5-second polling.
• Headroom page layout fix — Fixed h1 header clipped behind fixed navbar; corrected WCAG contrast violation on atelier-dark theme (contrast ratio was 1.20:1, now meets AA 4.5:1).
• macOS LAN firewall guard — Verifies actual Application Firewall allow state with socketfilterfw --getappblocked before using cdhash fast path; auto-refreshes exception when signature changes.
• Extension security hardening — os module added to import permission map; system/popen patterns added to dynamic exec detection; symlink escape prevention in rglob; strict action allowlist on permission approve/revoke endpoint.
• Dependency security — Removed headroom-ai[all] (pulled vulnerable litellm/sqlitedict); updated zeroconf to >=0.149.16.
• Navbar brand style — Fixed old-style "YU AI Manager" text in settings/diagnostics/crypto_tools pages (missing atelier-index.css).
