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)

+#
+# Components:
+#   - Whisper.cpp         — speech-to-text (Apple Silicon / CUDA optimised)
+#   - wyoming-faster-whisper — Wyoming STT adapter (port 10300)
+#   - Kokoro TTS          — fast text-to-speech via ONNX
+#   - wyoming-kokoro      — Wyoming TTS adapter (port 10301)
+#   - Chatterbox TTS      — voice cloning (MPS / CUDA)
+#   - openWakeWord        — always-on wake word detection
+#
+# Prerequisites:
+#   - P1 (homeai-infra) completed — Home Assistant running
+#   - P2 (homeai-llm) completed  — Ollama running
+#   - Python 3.10+ installed
+#   - macOS: Xcode Command Line Tools (for whisper.cpp compilation)
+#   - Linux: build-essential, cmake
