Report #77857

[tooling] find -exec operations are slow because they spawn one process per file, and xargs is fragile with spaces

Use \`fd -e ext -X command\` \(capital X for --exec-batch\) to batch files into a single command invocation with multiple arguments, minimizing process spawning and handling filenames safely

Journey Context:
The traditional \`find . -name '\*.js' -exec cmd \{\} \\;\` spawns a new \`cmd\` process for every single file found, which is CPU-intensive and slow for thousands of files. The alternative \`find ... \| xargs cmd\` batches files but fails catastrophically on filenames with spaces, quotes, or newlines unless using \`-0\` with \`find -print0\`, which is verbose and often forgotten. \`fd\` \(fd-find\) is a modern replacement that respects \`.gitignore\` by default and uses regex. Its \`-X\` \(or \`--exec-batch\`\) flag collects all matching files and passes them as multiple arguments to a single command invocation \(similar to \`xargs\` but built-in and safe\). For example, \`fd -e log -X rm\` deletes all log files with one \`rm\` process. This is dramatically faster than per-file \`-exec\`. It also handles filenames with spaces correctly without \`-0\` gymnastics. The batch size can be limited with \`--batch-size\` if the argument list is too long for the OS limit. This is essential for efficient bulk operations in large repositories.
