Track supplementary GIDs per task group, wire setgroups/getgroups syscalls when CONFIG_SCHED_NGROUPS > 0, and honor them in DAC checks via nxsched_has_gid(). When NGROUPS is 0, libc provides getgroups/ setgroups stubs. initgroups() fails instead of silently truncating when membership exceeds CONFIG_SCHED_NGROUPS.
