feat(pi-hermes-memory): 导入上游 v0.9.10 源码快照
从官方 Git 仓库导入 chandra447/pi-hermes-memory 在 tag v0.9.10 （df624056a2e8c68bc89ba0a81e1c120856ec9665，2026-10-02）的源码快照。 本次仅导入源码，尚未接入组合包：package.json、加载顺序、依赖与权限策略 均未改动。 - 原样导入 src/、tests/、docs/、scripts/、README、CHANGELOG、PLAN、 AGENTS 与 LICENSE；该快照共 156 个上游文件。 - 剔除嵌套 .git、上游 .github 工作流、.ralph/、.claude/、node_modules、 覆盖率与构建产物。 - 新增中文 UPSTREAM.md，记录来源，以及启用前必须完成的待决事项： 在 pi-compaction 之前注册加载顺序、better-sqlite3 版本与根 allowScripts 对齐、strip-ansi 解析确认。 - 说明选择 tag 而非 main 的原因：导入时上游 main 已领先至 24fcd8ad26fc27badb8d7dbaf8034645de07b893（2026-10-11），选 tag 是为 对应一个已发布、可复现的版本。 尚未接线。启用前还需反转 tests/extension-load.test.ts 中"不得加载 Hermes"的断言，并同步 pi-tool-search 分组、权限策略与文档。 验证：快照 156 个上游文件全部导入，目录内仅多出 UPSTREAM.md 一份； 已确认与上游 main 内容存在差异，证明取的是 tag 而非 main。

/**
|

* Behavior change under test (PR #184): reconcileMarkdownMemoryScope now

* runs its persistence inside DatabaseManager.withCorruptionRecovery().
|
||||
* Before this change, corruption errors ("database disk image is malformed",
|
||||
* SQLITE_CORRUPT, SQLITE_NOTADB) thrown during markdown reconciliation
|
||||
* surfaced as raw failures on every memory write — corruption recovery was
|
||||
* only wired into the session-indexing paths, so a corrupt sessions.db kept
|
||||
* failing markdown syncs until repaired by hand. Now the markdown reconcile
|
||||
* path participates in the same recovery: the corrupt database is
|
||||
* quarantined, rebuilt, and the reconcile is retried on a fresh handle, so
|
||||
* the memory entry is persisted instead of lost.
|
||||
*
|
||||
* The FTS5 soft fallback stays narrow: only genuine FTS query/index errors
|
||||
* (isFts5QueryError) degrade to a warned, repair-guided result. Corruption
|
||||
* signals never match that classifier, so they can never be swallowed into a
|
||||
* zero-count success here.
