## Summary This PR does the following: 1. Remove the symlinks from the `fuzz/` directory 2. Update `init-fuzzer.sh` script to create those symlinks 3. Update `fuzz/.gitignore` to ignore those corpus directories ## Test Plan Initialize the fuzzer: ```sh ./fuzz/init-fuzzer.sh ``` And, run a fuzz target: ```sh cargo +nightly fuzz run ruff_parse_simple -- -timeout=1 -only_ascii=1 ```
