fix: improve ABL and DF parser error handling

- Add try-catch blocks for ABL and DF parser loading
- Improve error messages when parsers fail to load
- Add warning messages to build script when WASM files are not found
- Ensure parsers gracefully skip when unavailable instead of throwing errors

This fixes the "No parser available for file extension" errors for .p, .w, .i, and .cls files
