/**
 * [ref] A9 域模块 —— 2c session-sync 面(sema-internal server/docs/DESIGN-session-sync.md §15 + §5–§10)。
 *
 * 路由:`/v1/sessions/:id/sync/{manifest,entries,import,plan,blobs,snapshots/:k/blobs/:b,import/:staging/entries}`。
 * 每条都像 fork/delete 一样 owner-gated;无持久 session store 时 501(能力面与路由解析同真值)。
 *
 * 单域独占状态(lens1 §C2 的 12 条里的 4 条)全在 `SessionSyncLocal`,每个 server 实例一份:
 * `pendingStagings`(Phase A→B 的 staging 绑定)、`importLeases`(per-session 导入租约)与它的两个操作。
