Add meteo domain types and MeteoService interface

[ultimate]

Motivation

• Introduce a typed domain model for meteorological and sea state data to standardize snapshot requests and responses.
• Provide consistent units, source metadata, and quality annotations to support multiple providers and fallbacks.
• Define a service contract for retrieving weather/sea snapshots to be implemented by providers.

Description

• Added a new app/domain/meteo module with exported types in index.ts and detailed definitions in types.ts.
• Defined request-related types including MeteoSnapshotRequest, MeteoSnapshotMode, and MeteoProviderName to control retrieval behavior.
• Introduced value, source, and unit abstractions with MeteoValue, MeteoSource, MeteoUnit, and quality/source enums to carry provenance and units.
• Defined domain models for MeteoWeather, MeteoWind, MeteoSea, MeteoTide, MeteoAstronomy, MeteoSnapshot, and the MeteoService interface with getSnapshot returning Promise<MeteoSnapshot>.

Testing

• No automated tests were run as part of this change.
