- Move existing OndselSolver, GNN ML layer, and tooling into GNN/ directory for integration in later phases - Add Create addon scaffold: package.xml, Init.py - Add expression DAG with eval, symbolic diff, simplification - Add parameter table with fixed/free variable tracking - Add quaternion rotation as polynomial Expr trees - Add RigidBody entity (7 DOF: position + unit quaternion) - Add constraint classes: Coincident, DistancePointPoint, Fixed - Add Newton-Raphson solver with symbolic Jacobian + numpy lstsq - Add pre-solve passes: substitution + single-equation - Add DOF counting via Jacobian SVD rank - Add KindredSolver IKCSolver bridge for kcsolve integration - Add 82 unit tests covering all modules Registers as 'kindred' solver via kcsolve.register_solver() when loaded by Create's addon_loader.
