Pull request overview

This PR integrates a fuzzing/ClusterFuzzLite workflow and related seed corpora into iccDEV, while updating parts of the CMake build to better support Emscripten/WASM constraints and static-only target consumption.

Changes:

Add libFuzzer harnesses, dictionaries/options, and seed corpus setup/testing scripts under Testing/Fuzzing/.
Add ClusterFuzzLite configuration (.clusterfuzzlite/*) and a GitHub Actions fuzzer smoke-test workflow.
Update CMake to generate version headers into the build directory and to improve portability for static-only builds / Emscripten.
