sara-tasks 2.7.0

//! `sara doctor` — a read-only health report over the memory store. It composes
//! the existing diagnostics (duplicate detection, the prune evaluation, the
//! embedding index, link integrity, recall activity, anchored-file drift) into one checklist, each
//! finding paired with the command that fixes it, plus the knowledge-reuse KPI.
//! Nothing here writes.
