feat: HomeDash - unified self-hosted navigation portal
Single-container navigation service combining: - Dashy dashboard + SearXNG metasearch + history sync API + admin WebUI - Go services for history/admin APIs, nginx as unified entry - Browser extensions (Chrome MV3 / Firefox MV2) with 30s batched sync - Production guide: portal-nginx unified auth reverse proxy + webui4frpc/frp tunnel - Fully sanitized (no internal IPs/domains/credentials)
