Summary

Adds SDK namespaces for the regional providers mtaapi.dev already serves, so the docs can show SDK code instead of curl. All of them go through the existing hostedJson (same auth headers and missing-apiKey error). Response types follow docs/openapi.json in mta-api.

const mta = new MTA({ apiKey: process.env.MTA_API_KEY })
await mta.path.arrivals({ station: "JSQ", direction: "to-ny" })
await mta.njTransit.rail.departures({ station: "NY", limit: 10 })
await mta.nycFerry.arrivals({ stop: "Wall St/Pier 11" })
await mta.citiBike.stations({ lat: 40.6923, lon: -73.9874, minBikes: 5, ebike: true })
await mta.lirr.departures({ stop: "Penn Station", route: "1", limit: 5 })
await mta.metroNorth.departures({ stop: "Grand Central" })

lirr and metroNorth share one CommuterRailClient with different base paths. Path params (route, Citi Bike id) are URL-encoded.

Bumps the version to 2.4.0. Publishing still needs a v2.4.0 tag after merge (publish.yml). The mta-api docs PR says "Requires mta-js 2.4.0", so publish before that one merges.

bun test index.test.ts (22 pass) and bun run typecheck pass. Hosted integration tests were added but not run locally because no MTA_API_KEY was set.
