v0.131.0

What's changed in 0.131.0

Added

• Add a DWD SWSMOS network (dwd/swsmos) exposing the road weather forecast (Straßenwetter-MOS)
  for DWD's ~1800 road weather stations. Each model run provides an hourly forecast out to +167 hours
  (selectable via issue, default: the latest run): air, dew-point and road surface temperature,
  liquid precipitation, precipitation probabilities and the road surface condition. This is the
  forecast counterpart to the DWD road observation network
• Add the DWD 10_minutes urban climate (Stadtklima) datasets to the dwd/observation network,
  served from DWD's climate_urban/ path (recent period only): urban_precipitation,
  urban_pressure, urban_solar, urban_temperature_air (incl. the new
  temperature_radiant_mean_2m parameter), urban_temperature_extreme, urban_temperature_soil,
  urban_wind and urban_wind_extreme. These complement the existing hourly urban datasets. The
  urban station-description lists are parsed by content because they frequently leave the optional
  date and Bundesland fields blank
• Add an IPMA (Portugal) observation provider (ipma/observation) backed by the key-less
  api.ipma.pt open-data JSON feeds. Provides near-real-time hourly observations (temperature,
  humidity, sea-level pressure, wind speed/direction, precipitation, global radiation) from ~222
  stations. Recent-only (a rolling ~1-day window), so a date range within the last day is required.
  The -99.0 missing sentinel becomes null and the 8-point wind-direction code is converted to
  degrees
• Add an LHMT (Lithuania) observation provider (lhmt/observation) backed by the key-less
  api.meteo.lt JSON REST API. Provides hourly observations (temperature, humidity, wind
  speed/gust/direction, cloud cover, sea-level pressure, precipitation, snow depth) from ~52
  stations, with historical data back to roughly 2016 fetched per station and day. Settled past days
  are cached indefinitely while the current day uses a short cache
• Add a Met Office (UK) observation provider (metoffice/observation) backed by the MIDAS Open
  archive on CEDA (UK Open Government Licence). Covers eight datasets across daily and hourly
  resolution (rain, temperature, weather, wind, radiation, soil temperature). Requires a free CEDA
  account (WD_AUTH__CEDA=<username>:<password>); the bearer token is minted from those credentials
  and cached in-process until shortly before it expires. Multiple report types per day are collapsed
  to one value per calendar day, multi-day rain accumulations are dropped, and native units are
  normalised (e.g. visibility from decametres to metres)

Changed

• Sharpen the interpolate/summarize endpoint descriptions (which become the MCP tool
  descriptions) and the MCP instructions so agents stop routing plain weather questions to them.
  stations -> values is now stated as the default for weather at a named place even when a
  specific past date is given, and interpolate/summarize are called out as opt-in estimates -- used
  only on explicit request or when no station with data is near the point -- because they add
  inaccuracy

Fixed

• Type the interpolate/summarize response-model items to match what the endpoints serialise, so
  their MCP output schemas stop rejecting valid results. _InterpolatedValuesItemDict and
  _SummarizedValuesItemDict now include the resolution/dataset keys (always present in the
  rows) and type value/distance_mean/distance/taken_station_id as nullable: interpolating or
  summarizing a point with no station in reach serialises null for those fields, which the previous
  non-null schema rejected (the same schema drift fixed for values in 0.130.0)
