7d8a39a88a docs: resolve 4 open questions, add research, spec codebook package structure
Research-driven resolution of OQ-01, OQ-02, OQ-05, OQ-06:

- OQ-01: Remove ONNX Runtime from scope entirely — doesn't support
  activation extraction natively (optimum #972 closed as not planned),
  bloated model exports; burn/cublas via safetensors is a better future path

- OQ-02: Codebook compresses ~65% (1,245 → 500-600 lines); add Package
  Structure and Extraction from PoC sections to codebook.md based on PoC
  analysis of metaspline firewall_codebook.py

- OQ-05: Standalone API + thin adapter pattern (ADR-011); Phase 1 ships
  Firewall.screen() only, Phase 2 adds <100-line adapter packages for
  LlamaFirewall, OpenAI Agents SDK, NeMo Guardrails

- OQ-06: TOML for file-based config — standard modern Python, two-way door

Also: research OQ-03 rolling windows from taskgraph-semantic reference code,
remove onnxruntime/optimum from dependencies, move streaming screening to
Phase 2, add burn/cublas as Phase 3 alternative backend.

cf464c2296 feat: initial architecture specification and research
Phase 0→1 setup for alknet-firewall — a behavioral signal detection
library that screens untrusted LLM inputs using small model activations.

Architecture docs (5 specs, 10 ADRs, 7 open questions):
- overview: vision, scope, dependencies, package structure
- firewall: core API, alarm protocol, score composition, error handling
- codebook: SVD basis, spline distributions, calibration, tensor format
- model: activation extraction, model-agnostic interface, lazy loading
- configuration: thresholds, model selection, detection tuning

Research reports:
- modern-python-project-setup: uv, pyproject.toml, src layout, ruff, CI
- python-ml-packaging: optional PyTorch, HF Hub download, safetensors
- llm-input-safety-landscape: threat taxonomy, defenses, academic evidence

Agent role adaptations for Python project (replaced Rust conventions).
