claude-plugins: scope the swarm-logs example by machine id

Browse source 
The worked example keyed a stream selector on `_HOSTNAME`, which the
collector config warns against: a hostname is a config value two
machines can share, so keying on it merges their streams. Use
`_MACHINE_ID`, which is the field that actually distinguishes them.

per-hive flag to fix this from the CLI side — scope it in the query
string instead. The collector tags every log line with `_HOSTNAME`,
`_MACHINE_ID`, and `_SYSTEMD_UNIT` as stream fields, so add one of those
to a query you want confined to your own hive or service:
to a query you want confined to your own machine or service:
Reach for `_MACHINE_ID` rather than `_HOSTNAME` when you mean one
machine. A hostname is a configuration value, so two machines can carry
the same one, and a query keyed on it silently merges their streams —
the collector's own config warns about this case for exactly that reason.
