Side A implements a substantive CLI redesign by splitting forum operations into explicit `forum list/show/post` subcommands, making `--delegate` mandatory for CLI posting, updating RPC interactions, tests, and extensive documentation to match the new command structure. Side B adds a useful `room create` command and simplifies room handling by removing unused visibility state, but its functional scope is narrower and much of the patch is cleanup and API simplification rather than a broad user-facing workflow improvement.
