Align Recorder.checkoutEveryNms default with rrweb behavior when maxSeconds is 0

[matux]

Description of the change

checkoutEveryNms defaults to 10 when maxSeconds is 0, inconsistent with rrweb’s expected behavior:

https://github.com/rrweb-io/rrweb/blob/76df9799ecc14930fa914e5623a73ea7726e3747/packages/rrweb/src/record/index.ts#L247-L252

    wrappedEmit = (r: eventWithoutTime, isCheckout?: boolean) => {
      ...
      const exceedTime =
        checkoutEveryNms &&
        e.timestamp - lastFullSnapshotEvent.timestamp > checkoutEveryNms;
      if (exceedCount || exceedTime) {
        takeFullSnapshot(true);
      }
    }

Where a checkoutEveryNms of 0 means a single initial full snapshot, and continuous event emission with no checkouts.
