feat(career): genre families — sub-genres inherit the family drill (#951)

The enrichment fallback made the passport rack real (hundreds of MB
sub-genres) but only the five exact umbrella keys carried Virtuoso
drills. Genres now resolve to a family by keyword substring (MB's
vocabulary is open — 'metalcore' must hit metal without an alias),
first-match-wins in list order ('blues rock' → blues), and inherit the
family's requirement from the same genres map. Exact entries still win;
per-instrument scoping unchanged; unmatched genres stay songs-only.

Data: families for metal (incl. djent/grindcore/thrash/doom), blues,
jazz (bebop/swing/bossa), funk (disco), rock (punk/grunge/shoegaze).
