feat(memory): message dual-visibility metadata system (M28)#818
Conversation
Add MessageMetadata with agent_visible/user_visible flags to Message. Compacted messages are marked agent_visible=false (hidden from LLM) while remaining user_visible=true (preserved for UI/TUI history). SQLite migration adds visibility columns with index on conversation_id. Semantic recall and keyword search now respect visibility boundaries. replace_conversation() persists compaction atomically.
