Reframe IB-WP-0014 from "in-repo S3/git backend adapters" to "durable archive
surface via artifact-store". The live infospace stays in a local working folder;
finalized snapshots are bundled into content-addressed artifact-store packages.
- New module infospace_bench.archive: archive_infospace(), list_archives(),
ArchiveRecord. Self-bootstraps a SQLite + local-FS registry under
output/archives/.store/ when no Registry is passed in.
- New output/archives/index.yaml records each archive event (package id,
manifest digest, retention class, included paths, file count, note).
- artifactstore added as a path dep; Python floor bumped to 3.12 to match.
- Makefile for venv-based dev setup; stack-and-commands.md updated.
- tests/test_archive.py covers index write, list, recursive-capture guard,
caller-supplied include, and empty-include error. Full suite 65 passed.
Remaining tasks (T03 list CLI, T04 restore, T05 docs) tracked in the workplan.
