PR D — Physics data attributes (rigid + cloth)

Labels: attrs, physics, config, project:newton
Milestone: PROJECT: Newton

Summary

Parse and apply per-element attributes:

• Rigid: data-phys-shape (circle|obb), data-phys-mass, data-phys-restitution, data-phys-friction.
• Cloth: data-cloth-damping (prep data-cloth-friction).
  Debug panel shows defaults for new activations; changing defaults affects new activations.

Acceptance Criteria

• Attributes parsed (clamped) and applied on activation
• Inspector shows parsed values
• Defaults reflected in Debug panel and respected

Tests (write first)

• parser.test: valid/invalid attrs → clamped values
• activationAttrs.test: activation uses attrs; defaults when missing
