Package search provides full-text search over local session transcripts. It is
read-only and agent-agnostic: it extracts the human-readable string values from
each JSONL line (skipping keys and obvious binary/base64 blobs) and matches a
literal or regular-expression query against them. It backs both `cct search` and
`export --match`.
Search runs the query against every session and returns the matches, sorted by
hit count (desc) then most-recent. Unreadable sessions are skipped silently.
