refactor(mapillary): remove the plain-English query feature

Street Level is imagery only from here on: coverage, sequences and the
embedded viewer. The Claude planner, map-feature and traffic-sign tiles,
the NDJSON feature stream, sprites, detection outlines and analyst records
go, along with @anthropic-ai/sdk, zod and the Anthropic key entry.
