commit b1508805707a53220e23290910d3699f747a8c2d
Author: Liang Zhang <zhangli...@apache.org>
AuthorDate: Sun Jul 5 22:02:19 2026 +0800

    Remove unused DistSQL label keywords (#39012)
    
    Remove LABEL, RELABEL, and UNLABEL from the shared DistSQL keyword grammar
    and the Proxy DistSQL reserved-word documentation. These tokens have no
    parser, statement, or executor support, so they should not be exposed as
    reserved RAL words.
