Jason 38d6dd0719 PR-AB.b expanded commit 6: subframe_pulse strip + stale MCU DIAG cleanup ...

Final cleanup pass for the PR-AB.b expanded bundle.

chirp_scheduler.v / radar_receiver_final.v: delete the unused subframe_pulse
output + its sibling subframe_id port. Both were declared on the scheduler
and bound at the radar_receiver_final.sched instance, but no downstream
module read them -- doppler_processor counts sub-frame boundaries
internally from new_chirp_frame + CHIRPS_PER_SUBFRAME=16. The stale
"// doppler picks up in PR-F" comment was aspirational; PR-F never wired
it. subframe_id demoted from output port to internal reg (still consumed
by the FSM's next_enabled_subframe helper).

tb_chirp_scheduler_handshake.v: drop the matching observer wires + port
bindings.

main.cpp: replace the F-2.1 "host_radar_mode = 2'b01 (auto-scan, FPGA-owned
chirp dispatch)" boot DIAG + 8-line comment block with a short comment
noting the mode register was retired in commit 1. The DIAG was asserting a
register that no longer exists.

Regression:
- FPGA iverilog: 43/0/0 (tb_chirp_scheduler_handshake 16/16)
- MCU: 51/0 (GPS) + 34/0 (AGC/safety/gap-3)

Closes the PR-AB.b expanded bundle (commits 1-6) on feat/dual-range-v2.
