Function fuchsia_fuzzctl::get_fuzzer_urls

pub fn get_fuzzer_urls(tests_json: &Option<String>) -> Result<Vec<Url>>

Gets URLs for available fuzzers.

Reads from the filesystem and parses the build metadata to produce a list of URLs for fuzzer packages. If tests_json is None, this will look for the FUCHSIA_DIR environment variable to locate tests.json within the build directory.

Returns an error if tests.json cannot be found, read, or parsed as valid JSON.
