Report #27084

[tooling] Processing thousands of files with -exec or xargs spawns too many processes and slows down

Use \`fd -X \{\} \+\` \(or \`--exec-batch\`\) to pass multiple filenames to a single command invocation, minimizing process spawning overhead similar to \`find -exec ... \+\`.

Journey Context:
Standard \`-exec\` without \`\+\` or \`xargs -n1\` invoke the target command once per file, causing massive fork/exec overhead when processing thousands of files. While \`find\` has \`-exec ... \+\`, \`fd\` provides \`-X\` \(capital X\) or \`--exec-batch\` which batches arguments similar to xargs but with fd's faster directory traversal. This feeds multiple files per command instance, drastically reducing runtime from minutes to seconds on large trees. The tradeoff is that the command must accept multiple file arguments at the end; for complex pipelines, you may still need \`-x\` \(per-file execution\). This is particularly effective when combined with tools like \`rm\`, \`chmod\`, or custom processing scripts that can handle batch input.
