Oura, Polar, WHOOP and Strava each keep the transport and endpoints in
`client.ts` and gain `wire-types.ts` (the record shapes) and `map.ts` (the
pure record-to-row mappers, no I/O). Google Health's 1,600-line client
becomes `budget.ts` (slice budget and outcome tally), `request.ts` (error
detail, retry, rate limits), `data-points.ts` (the paginated walker) and a
small `client.ts` for the profile and roll-up reads; its `export * from
"./mappers"` facade is gone and its importers name the module that defines
what they use.
The code moved verbatim; the mapper goldens written before the move and
the provider integration tests pass unchanged.
