[tooling] How to run commands on many files efficiently without xargs argument limits or quoting issues

Use \`fd pattern -x command \{\} \\;\` for parallel execution \(similar to find's \`-exec\` but parallel by default\) or \`fd pattern -X command \{\}\` for batching \(like xargs\). Example: \`fd '\\.py$' -x sed -i 's/foo/bar/g' \{\} \\;\` edits all Python files in parallel, safely handling filenames with spaces.

Journey Context:
Agents often use \`find . -name '\*.py' \| xargs sed -i 's/foo/bar/g'\`, which fails on filenames with spaces or when the argument list exceeds ARG\_MAX. While \`find -exec\` handles spaces, it processes files sequentially \(slow\) and the syntax is verbose. \`fd\` \(fd-find\) provides \`-x\` \(execute for each file, parallel by default\) and \`-X\` \(execute for all files as batch, like xargs but safer\). The key advantage is automatic escaping of filenames \(no quoting hell\) and parallel execution by default for \`-x\`, offering significant speedups for I/O-bound tasks. For CPU-bound tasks, the built-in parallelism is usually sufficient without manual \`parallel\` invocation.
