Summary by cubic

Make the Watcher work across Deno, browsers, and Node without the ws package. Adds a polling fallback, robust message parsing, and prevents duplicate document events.

• Bug Fixes

  • Load WebSocket from globalThis or node:undici; fall back to HTTP polling if unavailable.
  • Decode binary frames to UTF-8 before JSON parsing.
  • Deduplicate emitted documents across WS and polling.
  • Emit documents from snapshot responses and set binaryType to arraybuffer when supported.

• Dependencies

  • Remove ws and @types/ws.
  • Add a type shim for node:undici WebSocket.
  • Bump @mendable/firecrawl-js to 4.8.1.
