- add import-function tracking (WasmImportFunc) with signature/type checks - pre-collect call metadata, assign type indices, and register unresolved direct calls as imports - emit wasm import section (id=2) for imported functions - update call emission/indexing: defined calls are offset by import count; imported calls use import indices - adjust table/elem and export indices to account for imported functions - allow function-pointer resolution for imported symbols - add proper import-state cleanup on success and early error paths

This adds optimizations to the wasm32 backend. With that, computational kernels like mandelbrot (see attached) can go from 0.8x to 3.8x speedups.
