Codex b89477fb87 feat: web-vnc single-binary browser VNC gateway with password access
- Go stdlib-only gateway: serves noVNC client, password auth, WS<->TCP relay
- auth: PBKDF2-HMAC-SHA256 password hash, HMAC session cookies, login rate limit
- relay: hand-written RFC 6455 WebSocket + transparent RFB bridge
- vncspawner: cross-OS VNC server detection/launch (Windows/Linux/macOS)
- server: /login /logout /vnc /api/status routes, session middleware, embed.FS
- scripts: get-novnc, get-vnc (zip-verified), list-ips, open-firewall
- run.bat: one-click launcher (asks only password), lists access IPs
- README/AGENTS.md (Russian), .gitignore (root-anchored binaries)
