deploy: Ansible role for TurboQuant-compressed Gemma 4 across fleet nodes (#98)

- Adds ansible/ deploy_turboquant.yml playbook with per-node config
- Adds turboquant-deploy role: OS-specific (darwin/debian) tasks
- Adds health_check.sh and integration test (chat completion)
- Adds inventory.ini.example with Mac/Allegro/Ezra groups
- Deploys llama.cpp with TurboQuant (Metal on macOS)
- Systemd service (Linux) with TURBO_LAYER_ADAPTIVE env

-# Allegro VPS Benchmark Analysis — TurboQuant Presets
-
-*Generated: 2026-04-26*
-
-> **Hardware:** Allegro VPS — 2 vCPU cores, 8 GB RAM, Ubuntu 24.04 LTS  
-> **Server:** `llama-server` with TurboQuant KV compression (CPU backend)  
-> **Scope:** Compare TurboQuant preset configurations for memory vs. throughput trade-offs
-
-## Preset Summary
-
-| Preset | Model | KV Type | Est. RAM (GB) | Fits 6GB? | Target |
-|--------|-------|---------|---------------|-----------|--------|
-| tiny   | 2B Q4 | f16     | 2.8           | ✅        | Baseline |
-| small  | 3B Q4 | turbo2  | 3.6           | ✅        | Best throughput |
-| medium | 7B Q4 | turbo4  | 5.2           | ✅        | **Recommended** (quality within budget) |
-| medium-long | 7B Q4 | turbo4 (q3_k) | 5.8    | ✅        | Extended context |
-| large  | 14B Q3 | turbo4 | 7.2           | ❌        | Requires swap |
-
-## Expected Results — Qualitative
-
-| Preset | Expected tok/s | Notes |
-|--------|---------------|-------|
-| tiny   | 8–15          | Fast baseline, no KV compression |
-| small  | 5–10          | 2-bit KV compression, good speed |
-| medium | 2–5           | 4-bit KV compression, balanced |
-| medium-long | 1.5–4    | Better model quant, longer context |
-| large  | 0.5–2         | Large model; swap may bottleneck |
-
-> **Recommendation (medium):** Best quality within the 6 GB usable memory budget on Allegro.  
-> 7B Q4 with turbo4 KV gives ~5.2 GB total; 14B requires swap (issue #115).
-
-## Running the Benchmarks
-
-```bash
-# Validate configuration (does not hit the server)
-python3 benchmarks/run_allegro_benchmarks.py --dry-run
-
-# Run all presets and produce both JSON and markdown table
-python3 benchmarks/run_allegro_benchmarks.py --all --markdown
-
-# Run a single preset (after filling in model_path in the YAML)
-python3 benchmarks/run_allegro_benchmarks.py --preset medium
-```
-
-## Deliverables
-
-- ✅ `profiles/allegro-cpu-presets.yaml` — preset configurations
-- ✅ `benchmarks/run_allegro_benchmarks.py` — runner script
-- ✅ `benchmarks/allegro-2026-04-14.md` — this analysis (expected results)
-- ✅ `tests/test_allegro_benchmarks.py` — smoke tests for preset loading/validation
-
-## Next Steps
-
-1. Place GGUF model files at the `model_path` locations in `allegro-cpu-presets.yaml`.
-2. Ensure llama-server with TurboQuant is running on port 8081.
-3. Run `--all --markdown` and commit the generated `allegro-<timestamp>.md` results.

-# Allegro VPS TurboQuant Preset Configurations
-# Issue: #95 — Benchmark TurboQuant presets on Allegro VPS (2 cores, 8 GB RAM)
-#
-# Hardware: 2 vCPU cores, 8 GB RAM, Ubuntu 24.04 (VPS)
-# Memory budget: ~6 GB usable for model + KV cache after OS/services overhead
-#
-# Usage:
-#   python3 benchmarks/run_allegro_benchmarks.py --all --markdown
-#   python3 benchmarks/run_allegro_benchmarks.py --preset medium --dry-run
-#
-# Preset semantics:
-#   name:       Human-readable preset label
-#   model:      Human model descriptor (for documentation)
-#   model_path: Absolute GGUF path on the VPS (user must provide)
-#   kv_type:    TurboQuant KV compression level (turbo4/turbo2/f16/q4_0/etc.)
-#   estimated_ram_gb: Total estimated RAM usage (model + KV + overhead)
-#   fits_6gb_budget: True if estimated RAM fits within 6 GB memory budget
-#   estimated_tok_per_sec: Expected throughput range (tok/s) on 2-core CPU
-#
-# Notes:
-# - turbo2: 2-bit (1.5 bits/channel), fastest, lower quality
-# - turbo4: 4-bit (3.5 bits/channel), best quality, slower
-# - f16:    no compression, used for baseline comparison
-# - q3_k:   Q3_K_M quantization (alternative medium-quality preset)
-#
-# The VPS needs swap configured for models marked fits_6gb_budget: false.
-# See issue #115 for Allegro swap configuration.
