- Strip tools/schema.ts from 1831 to 65 lines (remove duplicate tool defs) - Fix tools/index.ts to export ALL_TOOLS from registry instead of schema - Fix renderJsx → renderJSX typo in tools/create.ts and structure.ts - Add geometry.ts with shared rotation/coordinate math utilities - Add isArrayMixed() helper to use-multi-props.ts, deduplicate FillSection/StrokeSection/EffectsSection - Fix broken test imports: use @open-pencil/core instead of relative paths into packages/core/src/ - Merge duplicate import statements across all test files - Export profiler internals and style-run helpers from core index.ts - Add 6 new test files: color, undo, snap, vector, style-runs, text-editor (98 new tests) - Update renderer-effects test for renderer/ directory split
