- Introduced a new `:context-ksqlite` module implementing `:context-api` with Ksqlite backend.
- Added a minimal schema (working_memory table + 2 indexes) for runtime context store: lightweight, excludes conversation/message/reflection tables, which are handled in separate modules.
- Initial version supports JVM, Linux, and Windows builds; migrates schema using SQLite PRAGMA.
- Includes fully autonomous in-memory schema migration and tests to validate operations like append, list, clear, and compact.
- Partial duplication of `:storage-ksqlite/KsqliteWorkingMemoryStore`; consumers will migrate incrementally.
