fix(local-knowledge): release 0.2.14 v2 scope upgrade

[oscharko]

Summary

• Fix Local Knowledge stores marked with reconstructive-columns/v2 so they upgrade to reconstructive-columns/v3 instead of failing with LOCAL_KNOWLEDGE_UNAVAILABLE.
• Bump the bundled release candidate to 0.2.14 and add release-impact metadata for the patch.
• Add regression coverage for opening a v2 encrypted store and sealing document blobs during upgrade.
