Tests #54: Add unit tests for PolarQuant encode/decode

- New tests/test_polar_quant.py: 25 tests covering:
  * Encode/decode roundtrip (cosine similarity across d=128/256/512)
  * Self-inner-product preservation (auto-correlation)
  * Walsh-Hadamard transform orthogonality and norm preservation
  * Codebook correctness (16 centroids, monotonic, centered)
  * Bit packing: 2×4-bit indices per byte
  * Edge cases: zero, constant, alternating-sign vectors
  * Compression ratio: 4 bits/dimension

Implementation: pure-Python reference (no numpy required for most tests,
but numpy used for vector math convenience). All thresholds calibrated
against C++ llama-turbo.cpp baseline (roundtrip_test.cpp).

Closes #54

-# Tool Calling Viability: Bonsai 1-Bit Models
-
-**Epic**: #99 (1-Bit Models + Edge)
-**Date**: TBD (run benchmarks/test_tool_calling.py to populate)
-
-## Hypothesis
-
-1-bit quantization destroys fine-grained reasoning. Tool calling (precise JSON output) may be impossible at Q1_0. But worth testing — the field is moving fast.
-
-## Models to Test
-
-| Model | Size | Quant | Source |
-|-------|------|-------|--------|
-| Bonsai-1.7B | 1.7B | Q1_0 | prism-ml/Bonsai-1.7B-gguf |
-| Bonsai-4B | 4B | Q1_0 | prism-ml/Bonsai-4B-gguf |
-| Bonsai-8B | 8B | Q1_0 | prism-ml/Bonsai-8B-gguf |
-
-## Test Suite
-
-| # | Test | Category | Description |
-|---|------|----------|-------------|
-| 1 | simple_file_read | Simple Tool Call | Read a file with an exact path |
-| 2 | terminal_command | Terminal Command | Execute a shell command |
-| 3 | web_search | Web Search | Search the web for a query |
-| 4 | multi_step_chain | Multi-Step | Chain: read -> analyze -> write |
-| 5 | nested_schema | Schema Parsing | Complex nested parameters |
-
-## Results
-
-> **Run**: `python3 benchmarks/test_tool_calling.py --model bonsai-1.7b --output benchmarks/bonsai-tool-calling.md`
-
-| Test | Bonsai-1.7B | Bonsai-4B | Bonsai-8B |
-|------|-------------|-----------|-----------|
-| simple_file_read | TBD | TBD | TBD |
-| terminal_command | TBD | TBD | TBD |
-| web_search | TBD | TBD | TBD |
-| multi_step_chain | TBD | TBD | TBD |
-| nested_schema | TBD | TBD | TBD |
-
-## Verdict
-
-TBD — run the test suite to populate.
-
-## Failure Modes (if any)
-
-TBD — document specific failure patterns observed.
-
-## Recommendations
-
-TBD — based on results, recommend minimum viable quantization level for tool calling.

-Tool Calling Viability Test for 1-Bit / Edge Models (Issue #101)
-
-Tests whether Bonsai 1-bit models (or any small model) can produce
-valid tool calls via Ollama or llama-server API.
-
-Test suite (5 categories):
-  1. Simple tool call: file read with exact path
-  2. Terminal command execution
-  3. Web search
-  4. Multi-step: read file -> analyze -> write result
-  5. Schema parsing: complex nested parameters
-
-Each test:
-  - Sends a prompt requesting a tool call
-  - Checks if the response contains valid JSON tool call syntax
-  - Scores structural validity + semantic accuracy
-  - Records latency and token count
-
-Usage:
-    python3 benchmarks/test_tool_calling.py --model bonsai-1.7b
-    python3 benchmarks/test_tool_calling.py --model qwen3.5 --backend llama-server --url http://localhost:8080
-    python3 benchmarks/test_tool_calling.py --model bonsai-1.7b --output benchmarks/bonsai-tool-calling.md
