BLUX Doctrine + Clarity Agent Architecture

Runtime: ca/runtime/agent.py orchestrates routing, governance (Doctrine), guard labeling, Lite planning, and LLM generation with safety overrides.
Safety: ca/safety/risk.py and ca/safety/protocols.py detect crisis/violence cues and override with safe responses before any model output.
Governance: Doctrine engine (doctrine/engine.py) loads rule bundles from doctrine/rules/ and produces allow/warn/block decisions with trace IDs.
Clarity Layer: ca/clarity/compass.py classifies user state; ca/clarity/structure.py enforces structured replies; ca/clarity/mirror.py offers reflective prompts.
Recovery: ca/recovery/support.py and ca/recovery/prep.py provide non-clinical coping plans and counselor-ready summaries.
LLM Backends: ca/llm/local.py and ca/llm/api.py implement pluggable model stubs via ca/llm/base.py.
Integrations: Stubs for Lite/Guard/Doctrine live under ca/integrations/ for future deep coupling without breaking current APIs.
