ci / JVM build + tests (push) Failing after 59s
- Removed `:message-store-api` module and associated classes (ConversationStore, ReflectionStore, Ids, etc.). - Migrated reusable components to `:journal-api` (conversation-related) and `:reflection-api` (reflection-related). - Updated imports and module dependencies across all projects to reflect new structure. - Adjusted build scripts and tests for compatibility with the new APIs.
