maksyuki 7592808464 feat: refactor JPEG table register bank and enhance flow script 
- Updated the JPEG table register bank module to use combinational logic for data handling and simplified the write logic for quantization, DC, and AC entries.
- Introduced a new function in the run_flow script to handle process termination more gracefully, including signal handling for interrupts.
- Enhanced the flow script to log peak RSS memory usage during execution.
- Modified multiple testbench files to include new storage access signals and improved the test logic for better validation of KWS and SRAM interactions.
- Updated tests to validate the new peak RSS memory logging in the flow script.
- Adjusted Yosys synthesis recipes to include timeout settings and ensure proper reporting of pre-memory synthesis outputs.

# APU block-level IHP130 synthesis + STA evidence flow (docs/ip/apu.md P8).
#
# Top: apb4_apu with parameter EnableP7 selected by APU_BLOCK_ENABLE_P7=0|1.
# Synthesis mirrors the whole-SoC Yosys flow (same script passes, same locked
# tools) with measured ABC deviations: the block recipe drops the "&fraig -x"
# SAT-sweeping pass (script/abc_balanced_apu_block.script), which does not
# terminate on the APU multiplier-dominated AIGs (14+ h on apu_kernel_engine
# alone with the stock recipe), and the giant KWS register-file window module
# is mapped in a second ABC phase with script/abc_balanced_apu_block_kws.script
# (block recipe minus "&dch -f", which likewise does not terminate on its
# 36.7M-AND network; measured 20.4 GB peak RSS, versus ~208 GB orphans with
# the stock recipe). STA runs OpenSTA at the 20.833 ns PCLK target
# with the block SDC in physical/smoke/sta/opensta/apu_block.sdc.
#
# Standalone use (until the root Makefile wires the include):
# make -f physical/smoke/syn/yosys/apu_block.mk CONFIG=configs/ci/ihp130.mk \
# apu-block-evidence
# Root-Makefile integration: include this file after yosys.mk/opensta.mk.
