Fixed
- Backups now include your memories. The backup command was archiving legacy file names and missed the actual database, so a restore could recover an empty store. It now captures the whole store directory crash-consistently (with its write-ahead log), skips rebuildable indexes, and warns loudly if no database is found.
- Prebuilt wheels build on Linux and macOS. Release wheels now build the bundled MCP wrapper on the host and install the x86_64 Rust target, so the macOS and Linux wheels build alongside the Windows one.
