feat: add --force flag to browsers update viewport resize

Bump go-sdk to v0.42.1 and expose the new `force` parameter on
`PATCH /browsers/{id}` viewport updates. When `--force` is passed
alongside `--viewport`, the resize proceeds even when a live view or
recording/replay is active — active recordings are gracefully stopped
and restarted as separate segments at the new resolution.

Made-with: Cursor
