v1.12.8

The one defect v1.12.7 knowingly left behind, and the last of the family: a script that assumed the
shape it happened to see first. This one never raised. It returned a confident wrong answer, at
high severity, to exactly the users whose markup was already right.

Fixed

• A LocalBusiness subtype now counts as a LocalBusiness. local_signals_checker.py matched the
  literal string LocalBusiness and nothing else, so a restaurant, dentist, plumber or bookshop
  carrying correct, more specific schema — the markup schema.org actually asks for — was told at
  high severity to add the schema it already had. maps_checker.py had known the subtype list
  since it was written; the two scripts simply disagreed about what a local business is.

  The taxonomy now lives once in scripts/jsonld.py as LOCAL_BUSINESS_TYPES (149 types, grouped
  by parent so it stays checkable against schema.org) and both scripts read it. Coverage is a strict
  superset of what maps_checker.py matched before: the five names in its private set that schema.org
  has never defined (Cafe, Gym, AutoBody, BarOrSalon, and a selfstorge typo) are kept as
  LOCAL_BUSINESS_ALIASES so nothing stops being detected — but a page using one now gets a medium
  finding naming the real type instead of silent acceptance.

Added

• jsonld.declared_types(), jsonld.local_business_types_in() and jsonld.is_local_business().
• local_signals_checker.py output gains localbusiness_types, and its recommendation names the
  subtype it found rather than saying "LocalBusiness" back at a page that says "Restaurant".
• tests/test_local_business_subtypes.py (78 tests; suite 300 -> 378), including a parametrised
  guard that every type maps_checker.py matched before this change is still matched.
