fix(showcase/langgraph-python): regenerate starter + bump catalog test counts

Re-run `generate-starters.ts` for langgraph-python to emit the
byoc_json_render_agent.py starter agent and register it in langgraph.json
(post-merge drift-check was failing because the starter hadn't been
regenerated after adding the byoc-json-render demo).

Bump generate-catalog.test LGP-feature-count assertions 32->33 and
wired-totals 176->177 / 31->32, unshipped 486->485 / 6->5 to match the
new manifest.
