chore: bump version to v2026.4.385 and refactor screenshot script}
- Bump version from v2026.4.383 to v2026.4.385 in package.json and README.md - Refactor screenshots.mjs to reuse a single page/tab instead of creating multiple pages, maintaining connection state across navigations - Reduce screenshot count from ~12 to 6 focused captures with diverse themes (Dark, Matrix, Enterprise, DarkNeu, DarkoBluo, Redis) - Add cleanup of old screenshot files on startup via rmSync - Extract waitLoaded() and waitConnected() helpers for reliable page readiness - Use nav bar click navigation instead of full page reloads to preserve WebSocket connections - Change shot() to accept an explicit index parameter instead of a module-level counter - Remove separate React settings/info screenshots, keep database and monitoring - Increase timeouts throughout for improved reliability
