Adds TreePlus::to_json() (nested objects with category, name, aggregated counts, components on file nodes, subtrees on containers) and a -j/--json CLI flag that prints the JSON document instead of the rendered tree and footer. Requested in issue #7; makes tprs scriptable in pipelines (jq, LLM tooling) without parsing the unicode render. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
