Replace internal math implementation with Hisabati

[waynemwashuma]

Objective

Refactors @wimaengine/math to use the standalone hisabati package as its underlying math implementation, reducing duplicated code and centralizing maintenance.

Solution

Changes Made

The following changes were introduced:

• Added hisabati as a dependency of @wimaengine/math and reexport its API.
• Removed tests belonging to the extracted math implementation.

Why This Approach

This solution was chosen because:

• It establishes Hisabati as the single source of truth for the shared math primitives.
• It reduces code duplication between Wima Engine and Hisabati.
• It allows the math implementation and its tests to be maintained independently.
• Re-exporting Hisabati from @wimaengine/math preserves the engine-facing public import path.
