for all 30+ sources
- Add implementation notes to §1.1 (Overpass), §1.2 (Playtomic tenants +
availability), §5.1 (Eurostat urb_cpop1 + ilc_di03), §5.2 (Census), §5.3 (ONS)
- Update §8 DuckDB integration table with extractor names and status
- Add §10 FX / Currency Rates: ECB SDMX endpoint and Frankfurter.app wrapper,
proposed landing format and stg_fx_rates staging model design

- Add section 9 to data-sources-inventory.md covering live API quirks:
Eurostat SDMX city labels response shape, ONS CSV download path (observations
API 404s), US Census ACS place endpoint, GeoNames cities15000 bulk format
- Add population coverage summary table and DuckDB glob limitation note
- fix(extract): census_usa + geonames write empty placeholder when credentials
absent so SQLMesh staging models don't fail with "no files found"
