naive_merge 不保证输出 chunk 在 token 上限内，当单行内容超过 chunk_token_num 时会产生超大 chunk，导致 LightRAG 报错 "Chunk token length 3140 exceeds chunk_token_size 1200"。 - nlp.py: 新增 hard_split_by_token_limit 公共硬切分函数 - general.py: 新增 _ensure_chunk_token_limit 兜底保护 - laws.py: 删除本地重复函数，改用 nlp 版本（DRY）

Summary
naive_merge在单行内容超过chunk_token_num时产生超大 chunk，导致 LightRAG 报错Chunk token length 3140 exceeds chunk_token_size 1200的问题nlp.hard_split_by_token_limit()公共硬切分函数（从laws.py提升，DRY）general.py添加_ensure_chunk_token_limit()兜底保护Background
LightRAG 上游有多个相关 issue（HKUDS/LightRAG#2387、#102、#2126）均未合并修复，需在预分块阶段自行兜底。
