feat: Update to production model stack and fix remaining inconsistencies

## Model Stack Updates (User's Actual Models)

Updated all documentation to reflect production models:
- Claude Opus 4.5 (primary reasoning)
- GPT 5.1 Codex max (code generation specialist)
- Gemini 3 Pro/Flash (multimodal, fast inference)
- Qwen3-235B (cost-effective, self-hostable)
- DeepSeek V3.2 (self-hosted, open weights)

### Files Updated:
- ADR-004: Full model groups, failover chains, cost tables
- ADR-007: Code example with correct model identifiers
- ADR-012: Cost tracking with new model prices
- ARCHITECTURE.md: Model groups, failover diagram
- IMPLEMENTATION_ROADMAP.md: External services list

## Architecture Diagram Updates

- Added LangGraph Runtime to orchestration layer
- Added technology labels (Type-Instance, transitions)

## Self-Hostability Table Expanded

Added entries for:
- LangGraph (MIT)
- transitions (MIT)
- DeepSeek V3.2 (MIT)
- Qwen3-235B (Apache 2.0)

## Metric Alignments

- Response time: Split into API (<200ms) and Agent (<10s/<60s)
- Cost per project: Adjusted to $100/sprint for Opus 4.5 pricing
- Added concurrent projects (10+) and agents (50+) metrics

## Infrastructure Updates

- Celery workers: 4-8 instances (was 2-4) across 4 queues
- MCP servers: Clarified Phase 2 + Phase 5 deployment
- Sync interval: Clarified 60s fallback + 15min reconciliation

## Context
Syndarix agents require access to large language models (LLMs) from multiple providers:
- **Anthropic** (Claude) - Primary provider
- **OpenAI** (GPT-4) - Fallback provider
- **Local models** (Ollama/Llama) - Cost optimization, privacy
- **Anthropic** (Claude Opus 4.5) - Primary provider, highest reasoning capability
- **Google** (Gemini 3 Pro/Flash) - Strong multimodal, fast inference
- **OpenAI** (GPT 5.1 Codex max) - Code generation specialist
- **Alibaba** (Qwen3-235B) - Cost-effective alternative
- **DeepSeek** (V3.2) - Open-weights, self-hostable option
We need a unified abstraction layer that provides:
- Consistent API across providers
