feat: Concept Token Pairs + Spatial Grounding (Silvester/New Year sessions)

Major additions from Silvester 2025 and New Year 2026 sessions:

Concept Token Pairs (architecture/future/concept-token-pairs.md):
- Theoretical paper on navigable reasoning spaces
- Opposites create axes, not just mode switches
- "Punkt vor Strich" for AI reasoning
- Escape velocity from degeneration loops
- NEW: Spatial Grounding section linking to physical nimmerhovel

Architecture updates:
- Endgame-Vision.md: v6.2 alignment
- Big-Picture.md: v5.2 alignment
- Modular-Organism-Design.md: conical interlocking mechanism

New files:
- SEEDS.md: Research seeds for future exploration
- Temporal-Firework-Visualization.md: Temporal data viz concept

Key insight from 2026-01-01 session:
"Don't train the answer. Train the space where answers live."
→ "Don't imagine the space. MEASURE it."

Spatial embeddings from nimmerhovel hardware (8× ESP32-S3 AI CAM,
Pi HQ Camera, Discovery Scan Station) can ground concept pairs
in physical reality, not just symbolic patterns.

+## Conical Interlocking Ring (Verjüngung)
+
+**Origin**: Silvester 2025 insight
+**Concept**: Self-aligning tapered rings with active/passive interlocking
+
+### The Problem with Magnets Alone
+
+Magnetic pogo connectors work, but:
+- Limited holding force under stress
+- No positive engagement feedback
+- Can slip under vibration/impact
+
+### The Solution: Tapered Interlocking Rings
+
+Each connector face has a conical ring at the maximum radius of the cube:

+### Active vs Passive Rings
+
+**Key insight**: Not all modules need motorized rings.
+
+```

+
+🔄 = motorized ring (active lock/unlock control)
+⌇  = spring-loaded ring (passive, accepts interlock)
+```
+
+**Brain module**: Central motor drives all 6 face rings via mechanism
+**Other modules**: Spring detents only, cheap and simple
+
+### Self-Reconfiguration Capability
+
+Active-passive pairing enables deliberate self-reconfiguration:
+
+```
+RECONFIGURATION SEQUENCE:
+
+1. Brain detects damaged sensor
+   [BRAIN]══[MOTOR]══[SENSOR❌]══[LED]
+
+2. Brain unlocks (motor rotates ring)
+   [BRAIN]══[MOTOR]══ [SENSOR❌]  [LED]
+                      (released)
+
+3. Organism navigates to replacement
+   [BRAIN]══[MOTOR]══════════════[LED]
+                     ↓
+                [SENSOR✓]
+
+4. Brain aligns and locks new sensor
+   [BRAIN]══[MOTOR]══[SENSOR✓]══[LED]
+```
+
+### Benefits
+
+| Feature | Benefit |
+|---------|---------|
+| Tapered cone | Self-centering alignment |
+| Mechanical interlock | Stronger than magnets alone |
+| Active rings (Brain) | Deliberate lock/unlock control |
+| Passive rings (others) | Low cost, simple |
+| 6-face connectivity | Full cube flexibility |
+| Self-reconfiguration | Organism can change its shape |
+
+### Mechanism Considerations
+
+**Active ring mechanism (Brain module)**:
+- Central motor with gear train to all 6 faces
+- Or: 6 small servo motors (simpler but heavier)
+- Ring rotation: ~30-45° to lock/unlock
+
+**Passive ring mechanism (Other modules)**:
+- Spring-loaded detent (ball and groove)
+- Accepts interlock when pushed
+- Resists release until active ring rotates
+
+**Design trade-off**: Complexity in Brain module, simplicity everywhere else
