makiandClaude Opus 4.7 7cd72323af Merge antenna muting mechanism onto 2026.w17 
Brings the O-RAN compliant antenna muting feature (originally introduced
on the 'new' branch) onto the latest upstream 2026.w17 tag.

Files added:
  openair1/PHY/NR_TRANSPORT/nr_antenna_state.{c,h}
  openair1/PHY/NR_TRANSPORT/nr_antenna_control.{c,h}

Files modified (integration hooks):
  CMakeLists.txt, executables/nr-gnb.c
  openair1/PHY/INIT/nr_init.c, openair1/PHY/defs_gNB.h
  openair1/PHY/MODULATION/{beamforming.c,nr_modulation.h,nr_beamforming.c}
  openair1/SCHED_NR/nr_ru_procedures.c
  openair2/LAYER2/NR_MAC_gNB/mac_proto.h
  openair2/LAYER2/NR_MAC_gNB/gNB_scheduler_{primitives,dlsch,uci}.c

Conflicts resolved:
  - defs_gNB.h: kept upstream's new headers + appended antenna_state.h
  - nr_init.c: dropped reference to upstream-removed nr_srs_info init,
    kept nr_init_antenna_state() call
  - beamforming.c: upstream moved nr_beam_precoding into new file
    nr_beamforming.c; nr_beam_precoding_with_muting added there with
    upstream's signature (no slot param)
  - nr_modulation.h: aligned _with_muting decl to upstream signature
  - nr_ru_procedures.c: muting check applied around upstream's new
    fft_shift in nr_feptx, and around per-port memcpy in nr_feptx_prec
  - gNB_scheduler_uci.c: SINR-based MCS hint uses get_dl_nrOfLayers(NULL,
    sched_ctrl, ...) since nrmac is not in scope at the call site
  - mac_proto.h: get_dl_nrOfLayers signature updated to take gNB_MAC_INST*
