Enum HostSelection 

pub enum HostSelection {
    Single(VpsName),
    All,
    Named(Vec<VpsName>),
    Tagged(Vec<HostTag>),
}

How multi-host SSH ops select target hosts (G-PAR-27 / G-PAR-31 / G-TYPE-09).

Workload: selection is pure local map lookup (tiny). Parallelism starts only after resolve_host_jobs when callers fan out via crate::concurrency::map_bounded.

Names/tags are refined at the CLI boundary (VpsName / HostTag); map keys stay owned String for wire/storage compatibility.

Variants

Single(VpsName)

One host by name (positional). Classic single-host JSON wire.

All

Every registered host. Batch JSON wire.

Named(Vec<VpsName>)

Explicit subset (--hosts). Batch JSON wire even if len == 1 (G-PAR-36).

Tagged(Vec<HostTag>)

Hosts matching any of the given tags (OR). Batch JSON wire (G-O2).
