Moves the firecrawl JS SDK from 4.44.0 to 4.48.0 (exact pin, lockfile updated) and releases 1.26.13.

4.48.0 adds the origin client option and keeps a caller's body origin, so once the agent origin change lands, SDK-routed CLI calls carry it too.

This supersedes the 4.46.0 bump in #325.

Build passes, and all 742 tests pass with no API key in the environment.
