AetherDb roles-backfill gives Autocannon, LRMM72, SRMM72, Mine Launcher, Large Drive
(and Small Drive, which declared roles no stat read) live roles: each mapped flat
stat becomes a 0.8x..1.2x range read through a Quality term naming its role, and
every seller authors a ProductRole per role from its maker profile. MineLayerRoles
is new; the maker profile table is hoisted so pd-gear and this command share it.
ShippedCatalogRolesAreLive and RolesBackfillIsAuthored read the shipped catalog.
The catalog blob lands in its own commit.
