[tooling] Parsing ripgrep output with regex or cut breaks on filenames with colons or newlines; need structured data

Add the \`--json\` flag to emit newline-delimited JSON objects. Pipe to \`jq -R 'fromjson?'\` to safely parse. Handle the four message types: \`begin\` \(file start\), \`match\` \(with submatches containing start/end byte offsets\), \`end\` \(file summary\), and \`summary\` \(totals\).

Journey Context:
Agents often script around \`grep -n\` or \`rg\` default output using \`awk -F: '\{print $1\}'\`, which fatally fails when filenames contain colons \(common in \`node\_modules\` or time-stamped logs\) or when lines contain the separator. The \`--json\` flag is deterministic: it outputs structured records with explicit fields for \`path\`, \`lines\`, \`line\_number\`, and byte offsets. The hard-won insight is that the JSON stream is not just an array of matches; it interleaves \`begin\` and \`end\` markers for each file, which is crucial for tracking context when using \`-C\` \(context lines\). Also, byte offsets are provided for precise manipulation, not just line numbers. This allows building robust tooling that never misparses filenames.
