Detailed Description

Storage backend registry: name -> factories.

[storage] backend names one entry.

fastmm::store::StoreRegistry::instance().add("clickhouse", &make_ch_backend, &make_ch_reader);

Nothing registers itself, for the same reason the strategy registry does not (a static library's self-registering object is dropped by the linker): fastmm::store::register_builtin_backends() adds the ones FastMM ships, and an out-of-tree backend calls add() before starting a session. The name "none" is reserved and never reaches the registry: it means no backend at all.
