- 重写 BLOCKED_WORDS 解析器：支持 /regex/flags 正则词条与纯文本词条混用，兼容中英文逗号（，/,）及逗号前后空格；正则词条内部的逗号不再被误切分 - 正则词条支持 i/m/s/u 等标志；自动剥离 g/y 标志避免 lastIndex 状态污染 - 非法正则自动降级为字面量匹配并输出警告，不再静默丢弃整条规则 - 新增生效诊断日志：规则解析结果、拦截总数/每条规则命中次数、拦截示例、无命中提示、配置无效警告，便于用户确认屏蔽词是否实际生效 - 更新 README 中 BLOCKED_WORDS 说明与示例 - 新增 test_blocked_words.mjs 覆盖 7 类解析场景（7/7 通过）

是的，把多余的删了吧 |
- 删除 README 中 TITLE_MAPPING_TABLE_URL / TITLE_MAPPING_TABLE_URL_CACHE_MINUTES 两条配置说明（对应功能未包含在本 PR） - test_blocked_words.mjs 的 7 类屏蔽词解析场景合并进 danmu_api/worker.test.js，删除独立测试文件（38/38 通过）

动机
当前 BLOCKED_WORDS 屏蔽词功能存在两个痛点：
split(/(?<=\/),(?=\/)/)切分，要求所有规则必须严格写成/a/,/b/格式。用户写纯文本词（如签到,打卡）时，整串会被当作一个无效正则静默丢弃，屏蔽词完全不生效且无任何提示；正则内部含逗号（如/a{1,2},b/）也会被误切分。改动内容
解析器重写（
danmu_api/utils/danmu-util.js）splitBlockedWords()：状态机式切分器/pattern/flags词条整体识别（词条内部的逗号、转义斜杠\/不作为分隔符）/等无法构成合法正则的片段按普通文本处理parseBlockedWord()：单条规则转换/pattern/或/pattern/i,m,s,u按正则解析（自动剥离 g/y 标志，避免 lastIndex 状态污染 test 结果）生效诊断日志
/打卡/ ×511, /签到/ ×49）、最多 3 条拦截示例（弹幕内容 ← 命中规则）文档与测试
danmu_api/worker.test.js中新增 BLOCKED_WORDS 测试：覆盖纯文本词、中英文逗号混用、正则+文本混合、正则内逗号、flags 剥离、非法正则降级等 7 类场景测试
node danmu_api/worker.test.js→ 38/38 通过（含新增屏蔽词测试，无回归）
