    Previous pattern N'%HumanEvents_%' had two issues:
      - unanchored leading % — a user session named "MyHumanEventsFoo"
        would match and get dropped.
      - unescaped _ — LIKE treats _ as a single-char wildcard, so
        "HumanEventsMonitor" (no literal underscore) would match via the
        trailing % + the _ wildcard eating any one character.

    Anchored to the prefix and escaped the literal underscore with a
    bracket class so an operator using HumanEvents-adjacent names for
    their own XE sessions isn't collateral damage.
