Add install script for one-command deployment

scripts/install.sh handles full fireclaw deployment on a fresh machine:
- System packages (curl, jq, git, ngircd)
- Node.js 20, Firecracker, Ollama
- ngircd config (nyx.fireclaw.local)
- Agent rootfs build (Alpine + Python + podman)
- VM snapshot, overseer systemd service, templates
- Optional --with-gpu flag for larger models

Usage: ./scripts/install.sh [--with-gpu]

 ### Multi-host agents
 Run agents on multiple machines (grogbox + odin). Overseer manages VMs across hosts via SSH. Agents on different hosts communicate via IRC federation.
 
-### GPU passthrough
-When/if grogbox gets a GPU: pass it through to a single agent VM for fast inference. That agent becomes the "smart" one, others stay on CPU. Or run Ollama with GPU on the host and all agents benefit.
+### GPU deployment
+Remote machine available: Xeon E5-1620 v4, 32GB RAM, Quadro P5000 (16GB VRAM). Enough for 14B-30B models at 2-5s inference. Standalone fireclaw deployment — its own ngircd, its own agents, completely independent from grogbox.
+
+### Install script
+`scripts/install.sh` — one-command deployment to new machines. Installs firecracker, ollama (with GPU if available), ngircd, Node.js, builds rootfs, configures everything. `curl -fsSL .../install.sh | bash` or just `./scripts/install.sh`. No Ansible dependency — plain bash.
