[tooling] Using \`find ... -exec\` or \`xargs\` fails on filenames with spaces/newlines or is slow due to process spawning overhead

Use \`fd -x \{\}\` for parallel execution per file, or \`fd -X \{\}\` for batch mode \(passing all files as arguments to one command\). Placeholders: \`\{\}\` \(full path\), \`\{.\}\` \(no extension\), \`\{/\}\` \(basename\), \`\{//\}\` \(parent dir\), \`\{/.\}\` \(basename no ext\). Example: \`fd -e svg -X convert \{\} output.png\` or \`fd -t f -x chmod 644 \{\}\`.

Journey Context:
Agents frequently script file operations using \`find . -name '\*.py' \| xargs grep\` or \`find -exec\`, which breaks when filenames contain spaces \(common in \`node\_modules\`, test fixtures, or user uploads\) or newlines \(allowed in Unix filenames\). \`fd\` solves this by defaulting to regex, respecting \`.gitignore\`, and providing the \`-x\` \(execute for each result in parallel\) and \`-X\` \(batch execute\) flags with shell-safe placeholder substitution. The hard-won insight is that \`-x\` spawns a new process for each file \(parallelizable with \`-j\`\), while \`-X\` passes all found files as arguments to a single command \(like \`xargs\`\), which is crucial for tools like \`tar -cf archive.tar\` where you want all files in one archive, not one archive per file. Also, the placeholder syntax \(\`\{.\}\`, \`\{/\}\`, etc.\) eliminates fragile \`basename\` or \`dirname\` subshells in scripts.
