[tooling] \`find -exec\` failing with 'Argument list too long' or forking per file \(slow\), while \`xargs\` is fragile with special filenames

Use \`fd --exec-batch\` \(or \`-X\`\) which batches results into minimal command invocations below ARG\_MAX limits while handling filenames safely via null-delimiters, avoiding the \`find -print0 \| xargs -0\` boilerplate and ARG\_MAX errors

Journey Context:
The classic \`find . -exec rm \{\} \\;\` is slow because it forks a process per file. \`find ... -exec ... \+\` helps by batching but hits system limits on argument length \(ARG\_MAX\) with many files, causing 'Argument list too long' errors. \`xargs\` helps with \`-0\` for null-delimited input, but composing it correctly with \`find -print0\` is verbose and error-prone \(forgetting \`-0\` breaks on spaces/newlines\). \`fd\` \(rust-based find replacement\) provides \`--exec-batch\` \(short \`-X\`\) which behaves like \`find ... \+\` but automatically chunks batches to stay under ARG\_MAX, and it accepts the \`\{\}\` placeholder for the file list. It handles null-delimiter safety internally and respects \`.gitignore\` by default. This allows safe bulk operations like \`fd -e log -X rm\` without ARG\_MAX errors or quoting issues. The tradeoff is requiring the \`fd\` binary, but it's available in all major package managers. For agents generating file manipulation scripts, it eliminates 'quoting hell' and 'argument too long' errors that are hard to debug and often only surface in production with large datasets.
