v0.15.0

Added

• Global Memory export / import. Back up the cross-session Global Memory to a JSON file, and import one back, from two buttons in the sidebar Memory tab. Import merges, skipping duplicates (by fact text) — non-destructive and idempotent. The file is a versioned envelope (kind + schema_version) so a wrong file (a session bundle, arbitrary JSON) is rejected with a clear message. Suited to backup and cross-machine migration of Global Memory. (ADR-0027.)

Removed

• Unused provenance fields dropped from Global Memory entries (SessionID, SourceTurnIndex, PromotedFromID). Written at promotion/extraction time but read by nothing, and — being references into the machine-local session namespace — unreliable across machines. Removing them eliminates a cross-machine collision hazard at the schema level. Backward compatible: existing global_memory.json files load fine and the obsolete keys drop out on next save. Source (trust tag) and ToolOriginated unchanged. (ADR-0028.)
