This pull request addresses issue #452, where the program produced no output when executed in wasm3. The following changes have been made to fix the issue:
Added missing function declarations in main.c to ensure proper compilation and linking.
Fixed zero-length buffer issue in fd_advise to prevent runtime errors.
Corrected WASI compilation target (unknown-wasi) to ensure successful build.
Improved error handling and ensured proper file descriptor management.
Verified execution with wasm3 --dir=./Data open.wasm, producing the expected console output.
These improvements make the program compile and run successfully in WASI environments while producing the expected debug output.
