Remove SQLite and Turso static data path

[gtokman]

Summary

• remove the libSQL/Turso database client, CLI, schema push, and persistent SQLite GTFS cache
• keep direct realtime feed support with optional in-memory staticData for metadata and local stop lookup
• update docs, examples, and tests around the hosted API as the production static-data path

Breaking changes

• removes MTA.database and databaseUrl/databaseAuthToken/databaseLocalPath options
• removes the mta-js CLI/bin and database import/push helpers
• local stops.near now requires caller-provided in-memory staticData; production stop search should use the hosted API

Verification

• bun test
• bun run typecheck
• rg stale Turso/libSQL/SQLite config references

Pull request overview

This PR removes the SQLite/Turso-backed static GTFS storage path (including schema/CLI helpers) and shifts the library toward (1) hosted API usage when apiKey is provided and (2) optional in-memory staticData seeding for lightweight local metadata/stop lookup.

Changes:

• Removed database/Turso/libSQL support, schema push utilities, and the mta-js CLI entrypoint.
• Reworked GTFSCache from a SQLite-backed store to an in-memory Map-based cache.
• Updated docs/examples/tests to emphasize the hosted API and in-memory static data seeding.
