Package orgscan wires up the full scanner+indexer stack against a live GitHub
org and collects graph statistics in a single pass. Used by the --benchmark
--org flag to produce the "Org Scan Stats" section of benchmark/RESULTS.md.
Run scans org with the given GitHub token, stores the graph in a temp SQLite
file, collects stats, and cleans up. ctx is forwarded to the scanner; set a
sensible deadline (e.g. 30 min) on the caller's context.
