v0.11.0 -> v0.12.0: startup hardware self-assessment (Roadmap J)

- hardware.py: assess_hardware() probes RAM, CPU, GPU VRAM (rocm-smi),
  llama-server, Qdrant, SearXNG reachability — writes hardware_state.json
- routers/hardware.py: GET /api/hardware (no auth) returns snapshot
- app.py: calls assess_hardware() in lifespan after init_db()
- 4 new tests: all services reachable, rocm-smi absent, llama unreachable,
  HTTP endpoint

app.py
