Report #12324

[tooling] find -exec runs commands sequentially causing slow batch operations; find -print0 \| xargs -0 fails on very large argument lists or complex parallel logic

Use \`fd pattern --type f -0 \| xargs -0 -P $\(nproc\) -I \{\} cmd \{\}\` for parallel, null-delimited safe file processing that saturates CPU cores while correctly handling filenames with spaces, quotes, or newlines

Journey Context:
Traditional \`find\` with \`-exec\` runs commands sequentially, creating a new process for each file, which is I/O-bound and slow. While \`find ... -print0 \| xargs -0\` solves the special-character handling problem, standard \`xargs\` without \`-P\` remains sequential. The \`-P\` flag enables parallel execution, but combining this with \`-I\` \(replace-str\) traditionally caused performance issues in older xargs implementations due to \`-L 1\` implications. Modern GNU xargs handles \`-P -I\` efficiently. \`fd\` \(fd-find\) provides better defaults than \`find\`: it respects \`.gitignore\`, uses regex by default, provides colorized output, and crucially guarantees null-delimited output with \`-0\` that pairs perfectly with \`xargs -0\`. The combination \`fd ... -0 \| xargs -0 -P $\(nproc\) -I \{\} ...\` provides a robust pattern for CPU-intensive batch processing \(image conversion, code linting on thousands of files\) that safely handles any valid Unix filename while maximizing throughput.
