check-translation.py: 11-check deterministic gate (line/paragraph/heading
parity, emphasis preservation, CJK and Chinese-punctuation leakage, bold
leakage, 万/亿-aware digit fidelity, terminology vs term map, bilingual
freshness). Built and calibrated on the 9-book review batch (2026-08-07).
AGENTS.md: add Workflow C (batch translate/review with herdr) — pane setup,
the three canonical prompts (translate/review/apply), and gotchas learned on
the 9-book run.
readme.md: document the gate in common tasks and point to Workflow C.
