/**
 * Factory function for creating a CompactionManager instance.

 * Convenience wrapper over `new CompactionManager(opts)` for symmetry

 *
 * NOTE: This factory is not yet wired to a consumer in the bootstrap layer.
 * Integration with the session bootstrap pipeline is the next step, the
 * CompactionManager will be instantiated per-session during session init
 * and attached to the session context for lifecycle event routing.
 *
 * @param opts - Manager options (see CompactionManagerOptions).
