Storage: move JSONL transcripts and the tool-result artifact store onto driver ports #453
Description
Part of tinyhumansai/openhuman#7522, tracked from tinyhumansai/openhuman#7783.
tinyagents#446 moved ArtifactOffload and generated media onto the BlobStore port. Two path-bound stores remain (see the PR's CHANGELOG 'Not yet moved'):
artifacts::tool_results::ToolResultArtifactStore: its pointers are file paths the hostfile_readopens, and pruning uses mtimes (blobs have none). Needs a host read tool and an age/retention design first.- The JSONL transcript writer/reader/
FileTranscriptLocator(about 12k lines insession::transcript, path-pervasive for adoption, spend and view). With a session provider (DriverSessionStores) transcripts already live insession_transcripts/session_transcript_entries; this item is the file-backed path used when no provider is installed.
Acceptance: neither store takes a filesystem path on its public surface; hosts hand it a driver port; legacy files are still imported once.

Architecture/refactor task: move the two remaining path-bound stores (artifacts::tool_results::ToolResultArtifactStore and the JSONL transcript writer/reader/FileTranscriptLocator in session::transcript) onto driver ports so neither takes a filesystem path on its public surface, while still importing legacy files once. Follow-up to tinyagents#446, which moved ArtifactOffload and generated media onto BlobStore; no functional breakage is reported, and the tool-result store explicitly needs a host read tool plus an age/retention design before it can move. No candidate duplicates or fixing PRs were provided, so duplicate_of and resolved_by are null.
