chore(台账): keyresp 合并后回填 RAM 台账与体积/覆盖率凭证

主干 0cabed0b 合入 task/keyresp-ui-key-latency 后按 C5 链补绿：
- @build 0 错 0 警（Code=246720 RW=2052 ZI=149708，与分支树同码）
- check_mem_numbers.py --write + ram_baseline.py --write/--update
- check_test_coverage.py --update-baseline（47/47，line 90.2%）
- add 后重打体积凭证（check_size_gate.py --stamp，同码免涨）
- check_doc_links.py --all 通过（214 文档 / 2966 引用）

RAM 增量归因见台账：本任务自身仅 ui_port.o +12 B 级，
其余为主干批 3 屏板链路累计（前笔 7708f12c 正文已如实说明）。
