#323 ported this branch's weather slices to dev and #333 built the wx/gwx convergence on them, so dev's wx, gwx, weather_common and location are a superset of the branch's: I took dev's side there, with the characterization goldens #333 regenerated. The rest:
- core.py: kept the template file and carried dev's knots option into modules/templates/default_config.ini.
- utils.py: kept the shared _geocode_city_steps and applied dev's zero-coordinate fix (is not None instead of truthiness) to its seven checks.
- weather_service.py: kept run_periodic/_cancel_tasks and took dev's per-point NWS coverage cache.
- solarforecast: restored self.geolocator, which #323 kept for local plugins and the merge would have dropped.
create_default_config held a 340-line config.ini as a string literal in core.py. The text now lives in a packaged template (added to package-data, which the packaging test checks) and the method writes it the same way. The file written on first run is byte-identical to before, checked against the literal's value from the previous commit.
