feat: add organ and nervous system modular architecture

Created modular architecture for organs (hardware) and nerves (behavioral primitives):

## Organ Architecture (Hardware Substrate)
- Created architecture/Organ-Index.md: hardware capabilities catalog
- Created architecture/organs/Speech-Organ.md: complete speech processing architecture
  - Atlas (RTX 2080 8GB) deployment
  - Whisper STT + Coqui TTS (GPU-accelerated, multilingual)
  - Kubernetes pod specs, Dockerfiles, service code
  - Heartbeat-bound queue processing, lifeforce-gated priority
  - German (Philosophy Valley) + English (Technical Cluster) routing
  - Database schemas, monitoring metrics

## Nervous System Architecture (Behavioral Primitives)
- Created architecture/nerves/Nervous-Index.md: nerve catalog and evolution framework
  - Deliberate (LLM) → Hybrid (heuristics) → Reflex (compiled) evolution
  - Lifeforce costs per state/transition
  - Organ dependency declarations
  - RLVR training integration
- Created architecture/nerves/Collision-Avoidance.md: complete example reflex nerve
  - Full state machine implementation (IDLE → DETECT → EVALUATE → EVADE → RESUME)
  - Evolution from 10 LF/1000ms (deliberate) → 2.5 LF/200ms (reflex)
  - Edge cases, training data, metrics
- Moved architecture/Nervous-Protocol.md → architecture/nerves/
  - Three-tier protocol belongs with nerve implementations
- Updated architecture/Nervous-System.md: added crosslinks to nerves/

## RAG Knowledge Pipeline
- Extended operations/RAG-as-Scaffold.md with "Knowledge Acquisition Pipeline" section
  - Vault extraction → Staging area → Progressive policy validation
  - Two-tier RAG (Discovered vs Hidden knowledge)
  - RAG utility measurement for LoRA training signals
  - Policy evolution triggers (increasing standards as Young Nyx matures)
  - Quality gates (mythology weight, AI assistant bias, topology safety)

## Architecture Principles
- Organs = hardware capabilities (Speech, Vision future)
- Nerves = behavioral state machines (Collision, Charging future)
- Both use lifeforce economy, heartbeat synchronization, priority queues
- Nerves compose organs into coherent behaviors
- Reflexes emerge from repetition (60% cost reduction, 80% latency reduction)

Documentation: ~3500 lines total
- Speech-Organ.md: ~850 lines
- Nervous-Index.md: ~500 lines
- Collision-Avoidance.md: ~800 lines
- RAG knowledge pipeline: ~260 lines
