Pull request overview
This PR converts 48 high-performance functions from JavaScript to TypeScript, adding WASM support as part of Phase 2 of a broader TypeScript migration effort. The conversion includes core algebra functions (sparse matrix operations, symbolic algebra, polynomial operations, decompositions), expression transforms, and AST node implementations.
Key changes:
- TypeScript conversion of sparse matrix algebra functions with comprehensive type definitions
- Migration of symbolic algebra operations (simplify, rationalize, derivative, resolve)
- Conversion of expression transform functions to TypeScript with proper interface definitions
- TypeScript implementation of AST nodes (SymbolNode, ParenthesisNode, RangeNode, RelationalNode)
