Alexander Whitestone d2706b18c2 feat: session power meter — 3D balance visualizer 
Adds the session power meter as both a 3D in-scene object and a HUD overlay.

3D scene object (positioned at -9, 0, 4 — visible from spawn):
- Vertical glass cylinder with GLSL energy-fill shader that clips
  fragments above the current power level
- Teal-to-purple gradient fill; turns red when power < 20%
- Animated scan lines, bright band at fill edge, pulse glow
- Floating orb that tracks fill height with gentle bob animation
- Dynamic point light attached to orb, color-shifts with power state
- 3 decorative spinning rings that dim above the fill level
- Canvas label: SESSION POWER / Fund once · Ask many

HUD panel (top-right corner):
- Live percentage + gradient bar with glowing tip indicator
- Credits counter (out of 10,000 CR)
- SOVEREIGN model tier badge
- Low-power warning (< 20%) with flashing icon
- "Fund once · Ask many models" tagline

Session power drains slowly over time (~16 min full drain) as a live
demo. Ready to wire to a real credits/subscription API.

Fixes #16
