Gap 7 MMCM jitter cleaner + CIC comb CREG pipeline + XDC clock-name fix
...
MMCM (Gap 7):
- Add adc_clk_mmcm.v: MMCME2_ADV wrapper (VCO=800MHz, CLKOUT0=400MHz)
- Modify ad9484_interface_400m.v: replace BUFG with MMCM path, gate reset on mmcm_locked
- Add adc_clk_mmcm.xdc: CDC false paths for clk_mmcm_out0 <-> clk_100m
XDC Fix (Build 19 WNS=-0.011 root cause):
- Remove conflicting create_generated_clock -name clk_400m_mmcm
- Replace all clk_400m_mmcm references with Vivado auto-generated clk_mmcm_out0
- CDC false paths now correctly apply to actual timing paths
CIC CREG Pipeline (Build 18 critical path fix):
- Explicit DSP48E1 for comb[0] with CREG=1/AREG=1/BREG=1/PREG=1
- Absorbs integrator_sampled_comb fabric FDRE into DSP48 C-port register
- Eliminates 0.643ns fabric->DSP routing delay (Build 18 tightest path)
- +1 cycle comb latency via data_valid_comb_0_out pipeline
- Move shared register declarations above ifndef SIMULATION (iverilog fix)
- Update golden data for +1 cycle CIC pipeline shift
Build scripts: build19_mmcm.tcl, build20_mmcm_creg.tcl
Regression: 18/18 FPGA pass, 20/20 MCU pass
Build 20 launched on remote Vivado (pending results)

Phase 1 hardware bring-up prep: ILA debug probes, CDC waivers, programming scripts
...
- Rename latency_buffer_2159 -> latency_buffer (module + file + all refs)
- Add CDC waivers for 5 verified false-positive criticals to XDC
- Add ILA debug probe insertion script (4 cores, 126 probe bits, 2 clock domains)
- Add FPGA programming script (7-step flow with DONE pin verification)
- Add ILA capture script (4 scenarios + health check, CSV export)
- Add debug_ila.xdc with MARK_DEBUG fallback attributes
- Full regression clean: 13/13 suites, 266/266 checks, 2048/2048 golden match

Fix all 10 CDC bugs from report_cdc audit, add overflow guard in range_bin_decimator
...
CDC fixes across 6 RTL files based on post-implementation report_cdc analysis:
- P0: sync stm32_mixers_enable and new_chirp_pulse to clk_120m via toggle CDC
in radar_transmitter, add ft601 reset synchronizer and USB holding
registers with proper edge detection in usb_data_interface
- P1: add ASYNC_REG to edge_detector, convert new_chirp_frame to toggle CDC,
fix USB valid edge detect to use fully-synced signal
- P2: register Gray encoding in cdc_adc_to_processing source domain, sync
ft601_txe and stm32_mixers_enable for status_reg in radar_system_top
- Safety: add in_bin_count overflow guard in range_bin_decimator to prevent
downstream BRAM corruption
All 13 regression test suites pass (159 individual tests).
