Subject: [PATCH] Make build scripts use incremental builds by default
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- build-wxuniversal-wasm.sh: Default to incremental, add --clean flag
- build-wasm-test.sh: Remove automatic clean, add --clean flag

Performance:
- No changes: ~0.3s (was full rebuild)
- Single file change: ~5s (just that file)
- Clean rebuild: use --clean flag
