Report #62618

[tooling] Using \`find ... \| xargs cmd\` or \`find -exec cmd \{\} \\;\` is slow due to process-per-file overhead or xargs argument limits

Use \`fd -X cmd \{\}\` \(or \`--exec-batch\`\) which batches files into a single command invocation with maximum argument limits automatically handled, avoiding the \`Argument list too long\` error and minimizing process spawning

Journey Context:
Traditional xargs requires careful handling of spaces in filenames \(-0 flag\) and often hits ARG\_MAX limits on large file sets. Find's \`-exec cmd \{\} \+\` is better but syntax is cumbersome. fd's -X flag \(inspired by GNU parallel's behavior\) collects all matched paths and invokes the command once \(or as few times as necessary to respect system limits\), automatically handling path separators and quoting. This is orders of magnitude faster than per-file exec \(e.g., chmod on 10k files: 10k processes vs 1 process\).
