fix: resolve smoke test failures

- Fixed memory backend API: getAll() now includes all memory types (lesson, gotcha, pattern, preference, discovery, context, ephemeral)
- Fixed memory test assertions: use MEMORY_TYPES.LESSON instead of undefined FACT, await retrieve() calls
- Added getAll() method to JSONBackend for grouped memory access
- Fixed InMemoryBackend to support all memory types in getAll()
- Fixed smoke test to properly await async methods and check correct properties
