Method Recall

internal/memory/sessionfiles.go:114–136

Recall walks the index and returns up to `limit` session records whose summary or tags match the query. Match is a case-insensitive substring scan, ordered most-recent first — enough for sub-thousand-session histories. Swap in a Bleve index or vector store when you outgrow it.

// scan, ordered most-recent first — enough for sub-thousand-session
