IB-WP-0014: archive remaining three infospaces

Capture the in-flight and legacy pilots as artifact-store packages, all at
retention class release-evidence (default expiry 2033-05-15).

- wealth-vsm-generation-pilot — pkg ed977a9c, 14 files (in flight, IB-WP-0013)
- wealth-vsm-legacy-slice     — pkg 9d114264, 10 files (legacy parity ref)
- bootstrap-pilot             — pkg fb31721e, 9  files (initial scaffold ref)

Each infospace now has its own self-contained .store/ (gitignored) and an
output/archives/index.yaml pointer log (tracked).
