SMTR's realtime feeds carry internal route keys, so a Rio card read
"Route O0731AAN0A" where riders know line SN731. Join both feeds to the
route_short_name in SMTR's static GTFS routes.txt (CC BY 4.0, same
publisher and terms). The keys cannot be parsed: O0014AAA0A is LECD135.
A 2026-11-04 snapshot found all 282 bus and 21 BRT routes in service in
the table; an unknown key still falls through raw.

Resolves the DATA_SOURCES.md conflict by keeping main's rewritten Transit
and Radio bullets and restating the count for this branch: eighteen feeds
covering seventeen regions (the two Rio feeds share one region).

Register Rio's two keyless GTFS-Realtime VehiclePositions feeds from the
city transport secretariat (SMTR): municipal buses (SPPO) and the
Mobi-Rio BRT, the Transit layer's first Latin American region.
Both feeds publish Position.speed in km/h instead of m/s. A new optional
registry field, speedUnit: 'kmh', makes buildTransitSnapshot convert it
once, so every speedMps consumer stays correct and other feeds are
untouched.
Document the source in DATA_SOURCES.md and update the region lists in
README.md and docs/CURRENT-STATE.md.
