docs: Architecture cleanup - ONE JOB per doc, links not echoes

Major documentation surgery following the cleanup principle:
"One job per doc. One home per concept. Links, not echoes."

Changes:
- Add Deployment-Architecture.md (THE WHERE - sole infrastructure truth)
- Endgame-Vision.md: 848→498 lines (-41%) - THE DREAM
- Gateway-Architecture.md: 537→395 lines (-26%) - THE ROUTING
- Nervous-System.md: 361→246 lines (-32%) - THE EVOLUTION
- Data-Architecture.md: 666→647 lines (-3%) - THE SCHEMA
- Message-Protocol-Design.md: 375→285 lines (-24%) - THE WIRE
- Attention-Flow.md: 557→493 lines (-11%) - THE BUDGET
- Cellular-Architecture.md: 891→855 lines (-4%) - THE HOW

Every doc now has ONE JOB statement, cross-references to canonical
homes, and lean footers. ~800 lines removed, zero concepts lost.

 **Connection to Gateway:** The tier system in this document (Cell → Nerve → Organism → Partnership) aligns with the Gateway's routing tiers. The [`Gateway`](Gateway-Architecture.md) routes sensory input to the appropriate tier based on node weight. See [`Gateway-Architecture.md`](Gateway-Architecture.md) for the unified tier model.

-## 📍 Document Status
-
-**Version:** 4.3 | **Created:** 2025-10-12 | **Updated:** 2026-01-03
-
-**Key Changes from v3**:
-- ❌ Cells as containers running genomes
-- ✅ Cells as atomic state machines wrapping hardware
-- ❌ Genomes as primitive operation sequences
-- ✅ Cells expose states; nerves compose them
-- ❌ Competition between organisms
-- ✅ Nerves evolve deliberate → reflex through verification
-- ❌ Specialists emerge from 10k competitions
-- ✅ Reflexes compile from 100+ successful nerve executions

-Where:
-- **Cells** expose hardware as state machines (atomic, verifiable)
-- **Nerves** compose cells into behaviors (discovered, evolved)
-- **Organisms** emerge from nerve interactions (identity through history)
-- **Lifeforce** flows through all layers (economics drive optimization)
-- **Reflexes** compile from lived experience (the body remembers)
-- **Feedback** loops continuously (cells → nerves → organisms → cells)
