feat: add agent estate section with 7 pages

Add agents/ directory with comprehensive documentation for all agents:
- agents/index.md — estate map and relationships
- agents/hermes-production.md — CT460 production Command Centre
- agents/hermes-chaos.md — CT450 experimental Chaos Lab
- agents/nanobot.md — CT333 Scout (quota notifications)
- agents/qwenpaw.md — CT465 multi-agent gateway
- agents/zeroclaw.md — CT333 autonomous daemon (TOML)
- agents/open-claw.md — VM 403 autonomous gateway

Updated index.md with Agent Estate section and links.
All pages follow existing SCHEMA.md conventions with YAML frontmatter.

+# Agent Estate
+
+> Map of all AI agents, their locations, and their roles in Anthony's setup.
+
+## Overview
+
+The agent estate consists of multiple Hermes instances, a QwenPaw deployment, ZeroClaw, Open-Claw, and Nanobot — each with a defined role and home container.
+
+## Agents
+
+| Agent | Container | Role | Status |
+|-------|-----------|------|--------|
+| [[agents/hermes-production]] | CT460 | Production Command Centre | Active |
+| [[agents/hermes-chaos]] | CT450 | Experimental Chaos Lab | Active |
+| [[agents/nanobot]] | CT333 | Scout (quota notifications, daily briefing) | Active |
+| [[agents/qwenpaw]] | CT465 | Multi-agent gateway | Active |
+| [[agents/zeroclaw]] | CT333 | Autonomous daemon (TOML config) | Active |
+| [[agents/open-claw]] | VM 403 | Autonomous gateway node | Active |
+
+## Shared Infrastructure
+
+All agents share:
+- [[systems/omniroute]] — model routing and provider management
+- [[systems/model-providers]] — LiteLLM + OmniRoute provider catalog
+- [[infrastructure/proxmox]] — PVE host and containers
+- [[infrastructure/tailscale]] — VPN and serve routes
+- [[infrastructure/domains-and-tunnels]] — Cloudflare Tunnel routing
+
+## Relationships
+
+- Hermes production (CT460) and Hermes Chaos (CT450) are separate Hermes instances with separate configs, skills, and cron jobs.
+- ZeroClaw and Nanobot share the same LXC container (CT333) but are different software with different configs (TOML vs JSON).
+- Open-Claw (VM 403) is a completely separate Docker-based gateway, not related to ZeroClaw despite the similar name.
+- QwenPaw (CT465) is a separate agent platform with its own workspace and model routing.
+
+## Key Rules
+
+- **Never assume one agent's config applies to another.** Each agent has its own config format, paths, and provider routing.
+- **CT333 has two agents.** ZeroClaw (root, TOML) and Nanobot (JSON) coexist. Do not restart one without checking the other.
+- **CT450 Chaos is experimental.** Changes here must not affect CT460 production without explicit approval.
+- **Phase Two (estate consolidation) is not approved.** CT450 duplicate cron jobs remain paused; CT460 counterparts remain enabled.
