oxi-cli 0.52.0

//! `/memory` — memory engine status and operations.
//!
//! Subcommands:
//!   `/memory`           — show working/episodic counts + last consolidation
//!   `/memory status`    — same as above
//!   `/memory sleep`     — trigger sleep consolidation (working → episodic)
//! Additional subcommands (from the omp `local-backend` port; require
//! the autonomous memory pipeline to have been spawned — see
//! `services::start_memory_pipeline`):
//!   `/memory view`       — show the active backend injection payload (live)
//!   `/memory stats`      — show backend-specific memory statistics
//!   `/memory diagnose`   — show backend-specific diagnostics
//!   `/memory clear`      — delete active backend memory data/artifacts
//!   `/memory enqueue`    — force-enqueue global consolidation work
//!   `/memory rebuild`    — alias for enqueue
//!   `/memory harmonize` — trigger SHMR harmonization
