[GH] (kvrocks/fix-xgroup-entries-read-clamp): Workflow run "CI" failed!

The GitHub Actions job "CI" on kvrocks.git/fix-xgroup-entries-read-clamp has failed.
Run started by GitHub user wengsht (triggered by jihuayu).

Head commit for run:

fix(stream): match Redis XINFO GROUPS lag when the group is behind the stream head

lag is entries_added - entries_read on an unsigned field. When the group's
last-delivered-id is behind the first live entry (a group created at 0, or one
whose entries_read was set inconsistently via XGROUP SETID/ENTRIESREAD),
trusting entries_read yields a wrong or underflowing lag.

Mirror Redis streamReplyWithCGLag: when the cursor and the max tombstone are
both behind the first entry, report lag = current stream length; and report
lag = 0 for an emptied stream. XINFO GROUPS lag now matches Redis exactly.
