feat: major formalization + FunctionGemma integration

Architecture Formalization:
- Created formalization/ section with mathematical foundations
- Lifeforce-Dynamics.md: λ as vitality ratio, stock-flow economics
- Grounded-World-Model.md: Blender boxes + SigLIP + T5Gemma2
- Embodiment-Pipeline.md: Isaac Sim as dreamstate validation
- Attention-Slumber-Prediction-Cycle.md: Last attention → slumber prediction

Promoted from Archive:
- Attention-Flow.md: 30-second budget, priority hierarchy (CANONICAL)
- Initial-Spark.md: v2.0 with FunctionGemma integration

Initial Spark v2.0 (Key Innovation):
- Two-Layer Architecture: FunctionGemma (270M) + Nemotron (31.6B)
- Solved cold-start problem: discoveries are PROFITABLE from heartbeat #1
- Typed function calls replace natural language probes
- Training data now structured (function→response pairs)

Big-Picture.md v5.1:
- Added Attention-Slumber-Prediction Cycle section
- Updated Related Documentation references

New Organ:
- Discovery-Scan-Station.md: rotating pedestal for object scanning (+31 LF net)
