Initial commit: localgenai stack

Containerized local LLM stack for the Framework Desktop / Strix Halo,
plus the OpenCode harness on the Mac side.

- pyinfra/framework/: pyinfra deploy targeting the box
  - llama.cpp (Vulkan), vLLM (ROCm), Ollama (ROCm with HSA override
    for gfx1151), OpenWebUI
  - Beszel (host + container + AMD GPU dashboard via sysfs)
  - OpenLIT (LLM fleet metrics)
  - Phoenix (per-trace agent waterfall)
  - OpenHands (autonomous agent in a Docker sandbox)
- opencode/: OpenCode config + Phoenix bridge plugin (OTel exporter)
  - install.sh deploys to ~/.config/opencode/
- StrixHaloSetup.md / StrixHaloMemory.md / Roadmap.md / TODO.md:
  documentation and planning
- testing/qwen3-coder-30b/: small evaluation harness

+# Arize Phoenix — per-trace agent waterfall / flamegraph viz.
+# https://github.com/Arize-ai/phoenix
+#
+# Picked over Langfuse for "show me one OpenCode turn as a tree":
+#   - Single container vs Langfuse's six (Postgres+ClickHouse+Redis+MinIO+web+worker).
+#   - First-class ingestion of Vercel AI SDK spans (which is what OpenCode
+#     emits under the hood when experimental.openTelemetry=true).
+#   - Best-in-class waterfall + agent-graph view for nested LLM/tool calls.
+#
+# Complements OpenLIT, doesn't replace it: OpenLIT is the fleet-metrics
+# layer (cost / tokens / latency aggregated across sessions). Phoenix is
+# the per-prompt debugger (see what one turn actually did).
+#
+# Bring-up: `docker compose up -d` — no first-run setup needed; UI prompts
+# for project name on first trace ingest. Storage is SQLite at /data.
