Lineage v0.1.12

• Add named runtime profiles that bind environment, SQLite, media root, service origin, and expected runtime identity without allowing silent path drift.
• Enforce a single cross-process writer lease per profile and route profile-bound mutations through the authenticated managed service while keeping inspections read-only.
• Add opt-in lineage.selection_packet.v2 exports whose stable semantic identity binds ordered selections to their current attempts and checksums for durable GrowthOps handoff receipts.
