docs: update README, CLAUDE.md, backlog, and .env.example

- README: add all features, correct tech stack (axios/setInterval), add IP addresses section, fix API routes
- CLAUDE.md: fix architecture, remove SWR references, fix env var names, add IP address patterns
- backlog: remove ip6= mention, clean duplicate entries, mark done
- .env.example: remove unused PROXMOX_CONSOLE_TOKEN

 ## Features
 
-- **Node overview** — CPU, memory, uptime, and load for each Proxmox node
+- **Node overview** — CPU, memory, uptime, and load for each Proxmox node, grouped into collapsible cards
 - **VM & LXC tracking** — status, resource usage across all nodes
 - **Summary cards** — total nodes, running/stopped VMs, aggregate memory
-- **Auto-refresh** — polling every 30s (configurable)
-- **Tabbed navigation** — switch between Nodes, VMs, and LXCs
+- **Per-VM/LXC IP addresses** — IPv4 from guest agent (QEMU) or network config (LXC), displayed below VM/LXC name
+- **Power control** — Start/stop/restart buttons per row
+- **Console links** — Opens Proxmox web UI console in a new tab
+- **Search / filter** — Client-side filtering by name, node, or status with auto-expand
+- **Group by node** — Collapsible node cards with running/stopped subtotals
+- **Manual refresh** — Button in header to refresh all data
+- **Custom poll interval** — Adjustable polling interval (default 30s) via header input
+- **Uptime display** — Formatted as "Xd Yh Zm"
+- **Auto-refresh** — Manual `setInterval` polling every 30s (configurable)
 
 ## Tech Stack
 
 - **Framework** — Next.js 15 (App Router)
 - **UI** — React 19, Tailwind CSS 4
-- **Data fetching** — SWR (auto-refresh), Axios
+- **Data fetching** — Axios with manual `setInterval` polling
 - **Proxmox** — API2 Token-based auth
