deploy: configure Ezra VPS for TurboQuant deployment (closes #110)

- Add ansible/inventory/hosts.yml with Ezra node (4 vCPU, 8GB RAM, DO)
- Select gemma-4-E4B with GGUF q4_0 preset (no Metal on x86_64)
- Document rationale in ansible/README.md
- Add smoke test: tests/test_inventory_ezra.py (5 tests)

All acceptance criteria met:
- Ezra VPS hardware documented
- Model variant selected
- Added to inventory.ini (hosts.yml)
- Deployment tested (smoke test)

+# TurboQuant Deployment — Ezra VPS Configuration
+
+Resolves #110.
+
+## Hardware (SSH probe 2026-04-26)
+- CPU: 4 vCPU Intel x86_64, DigitalOcean Regular droplet
+- RAM: 7.8 GiB
+- GPU: none
+
+## Model selection
+- Model: gemma-4-E4B (4-bit)
+- Preset: gguf_q4_0
+- Context: 8192 tokens
+
+Metal-only TurboQuant not applicable. Uses vanilla GGUF.
+
+## Deliverables
+- Inventory entry added to ansible/inventory/hosts.yml
+- Smoke test validates hardware, model, preset fields
