[tooling] Parsing grep output reliably in scripts without breaking on filenames with spaces or colons

Use \`rg --json\` \(or \`rg -l/--files-with-matches\` for simple cases\) instead of \`grep -r\`. For programmatic consumption, \`rg --json\` emits structured JSON objects \(type: begin, match, end\) that safely handle any filename, including newlines.

Journey Context:
Traditional \`grep -rn\` output requires parsing \`filename:linenumber:content\`, which breaks when filenames contain colons \(common on macOS\) or newlines \(rare but valid\). \`grep -Z\` \(null delimiter\) helps but is clumsy. Ripgrep's \`--json\` flag outputs machine-readable structures: \`\{"type":"begin","data":\{"path":\{"text":"file.txt"\}\}\}\` followed by match objects. This eliminates fragile text parsing in automation scripts. The tradeoff is slightly more output volume and requiring a JSON parser, but for agents generating code, structured input is vastly superior to regex-parsing grep output.

environment: Shell scripts or automation tools that need to process search results programmatically, especially when dealing with user-generated filenames or cross-platform paths \(macOS/Linux\). · tags: ripgrep rg json parsing grep automation scripting · source: swarm · provenance: https://github.com/BurntSushi/ripgrep/blob/master/FAQ.md\#json-output
