drive: add save + retype; point docs/skills at the ergonomic frontend

Round out idatui.drive with 'save' and 'retype <fn> <proto>' so the whole
common RE loop (orient/understand/act/persist) has a terse command. Update
docs/RPC.md and both skills (idatui, idatui-rpc) to recommend idatui.drive
as the day-to-day driving surface, with rpcclient/raw as the fallback for
unwrapped verbs.
