Per-snapshot size + file-count come from the embedded summary block
restic added to 'snapshots --json' in 0.17 (the source comment in
internal/restic/snapshots.go incorrectly said 0.16+). Hosts running
0.16.x leave those columns blank.
- Fix the snapshots.go doc comment: '0.16+' -> '0.17+'.
- hostDetailPage carries a LegacyRestic bool computed from the host's
reported ResticVersion via Env.AtLeastVersion(0, 17). Empty version
also counts as legacy (conservative default).
- Template attaches title='Needs restic 0.17+ on the agent host. This
host runs <ver>.' + cursor:help on the SIZE / FILES headers when
the flag is true. Hosts already on 0.17+ get no tooltip and no
extra styling.
A host upgrading restic to 0.17+ gets the columns populated on the
next backup automatically — no further code change needed.
