Metadata

Commit Message: feat(ui): implement window registry and layout engine
Branch: feature/window-layout

Background and Context

The specification describes a WindowRegistry for declarative window definitions and a
LayoutConstraintEngine that resolves window positions and sizes using a 5-pass
constraint satisfaction algorithm.

Acceptance Criteria

WindowDefinition data model with layout tier membership
WindowRegistry for registering and querying window definitions
LayoutConstraint data model with min/max/preferred dimensions and weights
5-pass resolution algorithm (tier selection, enumeration, fixed allocation, flex distribution, position assignment)
Adaptive resizing on NAWS terminal dimension changes
BDD test coverage

Subtasks

Implement WindowDefinition and WindowRegistry
Implement LayoutConstraint and 5-pass algorithm
Define tier constraint sets
Implement adaptive resizing

Definition of Done
