assistant settings: a cloud switch per tool; cloud Prefer rows show

The Prefer rows for cloud models never built: the shell's JS engine has
no Array.prototype.flatMap, and the Repeater's model threw a TypeError
(seen in qs log). The ids are now joined with reduce in the module.

Each tool row gains a cloud switch, applied on Save after the renames:
it writes or drops a top-level cloud = true, validated with tomllib and
replaced atomically, on name.toml or name.toml.off.
