Batch-compile all ~64 IR primitives into a single WASM module at startup. Replaces 64 separate Module::new + Instance::new with 1 of each. Reuses compile_consolidated_module() directly, removed compile_core_module() stub. Boot time: 7.7ms -> 0.6ms (release), test suite: 5.1s -> 1.5s (debug). 13 of 14 optimizations now implemented. 392 tests passing.
