v2.10.0

Added

• New tool: airport_lookup — look up an airport by IATA code (3 letters, e.g. LHR), ICAO code (4 chars, e.g. EGLL), or name/city search. Returns the full record (both codes, name, type, municipality, region, country, latitude/longitude, elevation), with ranked candidates for ambiguous names and an optional type filter. Proxies GET /api/airports.
• New tool: nearest_airport — find the airports nearest to a caller-provided latitude/longitude, sorted by great-circle (haversine) distance with distance_km on each result. Optional radius_km, max_results (1–50, default 10) and type filter. Coordinates are input only — never stored or logged. Proxies GET /api/nearest-airport.
• Both tools are backed by the public-domain OurAirports dataset (85,555 airports), cross-checked against OpenFlights + Wikidata, and registered via server.registerTool() with full output schemas + structuredContent and a _source citing OurAirports.
• Tool count: 22 → 24 (REST surface: 21 → 23 endpoints).
