Add self-deploying setup scripts for all sub-projects (P1-P8)

- Root setup.sh orchestrator with per-phase dispatch (./setup.sh p1..p8 | all | status)
- Makefile convenience targets (make infra, make llm, make status, etc.)
- scripts/common.sh: shared bash library for OS detection, Docker helpers,
  service management (launchd/systemd), package install, env management
- .env.example + .gitignore: shared config template and secret exclusions

P1 (homeai-infra): full implementation
- docker-compose.yml: Uptime Kuma, code-server, n8n
- Note: Home Assistant, Portainer, Gitea are pre-existing instances
- setup.sh: Docker install, homeai network, container health checks

P2 (homeai-llm): full implementation
- Ollama native install with CUDA/ROCm/Metal auto-detection
- launchd plist (macOS) + systemd service (Linux) for auto-start
- scripts/pull-models.sh: idempotent model puller from manifest
- scripts/benchmark.sh: tokens/sec measurement per model
- Open WebUI on port 3030 (avoids Gitea :3000 conflict)

+# homeai-images/setup.sh — P8: ComfyUI + SDXL/Flux + character LoRA
+#
+# Components:
+#   - ComfyUI           — image generation UI + API (port 8188)
+#   - SDXL, Flux.1      — base checkpoints
+#   - ControlNet        — pose/depth guidance
+#   - aria LoRA         — character-consistent fine-tune
+#   - comfyui.py skill  — OpenClaw integration
+#   - workflows/        — saved workflows (quick, portrait, scene, upscale)
+#
+# Prerequisites:
+#   - P4 (homeai-agent) — OpenClaw running (for skill integration)
+#   - Python 3.10+
+#   - macOS: Metal GPU (MPS) — runs natively
+#   - Linux: CUDA GPU recommended (NVIDIA); CPU is very slow for image gen
+#
+# ComfyUI runs NATIVELY (not Docker) for GPU acceleration.
