Add infrastructure documentation (INFRASTRUCTURE.md)

[evansenter]

Problem

The current setup for mac-mini involves multiple services (agent-event-bus, agent-session-analytics, agent-memory-store, OpenClaw gateway) that aren't documented in one place. Recreating the server requires tribal knowledge.

Proposal

Add docs/INFRASTRUCTURE.md documenting:

What runs where

• mac-mini (server): agent-event-bus (:8080), agent-session-analytics (:8081), agent-memory-store (:8083), OpenClaw gateway (:18789)
• Client machines: Connect via Tailscale URLs

Tailscale serve configuration

tailscale serve --bg --set-path /agent-event-bus http://127.0.0.1:8080
tailscale serve --bg --set-path /agent-session-analytics http://127.0.0.1:8081
tailscale serve --bg --set-path /agent-memory-store http://127.0.0.1:8083
tailscale serve --bg / http://127.0.0.1:18789

Server bootstrap steps

1. Clone + make install-server for each service
2. Configure tailscale serve paths
3. Verify LaunchAgents running

LaunchAgent plists

Located in ~/Library/LaunchAgents/:

• com.evansenter.agent-event-bus
• com.evansenter.agent-session-analytics
• com.evansenter.agent-memory-store
• OpenClaw managed by its own installer

Client setup

• Already covered in CLAUDE.md for OpenClaw
• bootstrap.sh configures settings.local.json with remote MCP URLs for non-gateway hosts

Context

Discovered this gap when reviewing infrastructure setup. Currently the only docs are scattered across individual project READMEs and brief mentions in CLAUDE.md.
