## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
Implemented a mathematical framework for visualizing how constraints propagate through decision pipelines. Each decision point creates a "possibility cone" - a light-cone-like structure representing reachable futures. Subsequent constraints act as apertures that narrow these cones.

Key components:
- types.ts: Core type definitions (SpacePoint, PossibilityCone, ConeConstraint, ConeIntersection, etc.)
- geometry.ts: Vector operations, cone math, conic sections, intersection algorithms
- pipeline.ts: ConstraintPipelineManager for constraint propagation through stages
- optimization.ts: PathOptimizer with A*, Dijkstra, gradient descent, simulated annealing
- visualization.ts: Rendering helpers for 2D/3D projections, SVG paths, canvas rendering

Features:
- N-dimensional possibility space with configurable dimensions
- Constraint pipeline with stages and dependency analysis
- Multiple constraint surface types (hyperplane, sphere, cone, custom)
- Value-weighted path optimization through constrained space
- Waist detection (bottleneck finding)
- Caustic point detection (convergence analysis)
- Animation helpers for cone narrowing visualization
