统一 SQL 查询与服务层的标题归一化。

如果已有标题以制表符、换行符或不间断空格开头,TRIM(title) 不会将其移除,但 saveWithDedupe 使用的 JavaScript trim() 会移除。新查询因此找不到原本符合去重条件的行,后续写入会静默创建重复记忆。请让查询键与服务层使用同一归一化规则,并补充非普通空格的回归用例。(sqlite.org)

Review comment at @dsh-mneme/src/store.js at line 1666:
更新 `saveWithDedupe` 中按标题查重的 SQL,使查询键与 JavaScript `trim()`
使用一致的归一化规则,确保标题开头或结尾的制表符、换行符及不间断空格也会被忽略;补充这些非普通空格的回归用例,验证不会创建重复记忆。

为定向查询建立匹配索引。

saveWithDedupe 的每次普通写入都会调用 activeByTypeAndTitle。当前查询只能按 type 定位,再扫描该类型的行并计算 TRIM(title)。同一类型的记忆增长时,写入成本会随之增长。

请添加覆盖活跃行的部分表达式索引:

建议的索引
 CREATE INDEX IF NOT EXISTS idx_memories_type ON memories(type);
+CREATE INDEX IF NOT EXISTS idx_memories_active_type_trim_title
+  ON memories(type, TRIM(title))
+  WHERE forgotten = 0 AND archived = 0;
