Function format_runs 

pub fn format_runs(
    runs: &[RunListEntry],
    finished: &[RunListEntry],
    health: &DaemonHealth,
    now: i64,
) -> String

Render a run listing as an aligned table (or a friendly note when empty), with the daemon’s own health underneath when it has something to say.

finished are runs the daemon has unloaded but still remembers. They are listed after the live ones rather than left out, because “the run I started died on its first inference” and “there is no such run” are the two answers issue #205’s scheduler could not tell apart, and an empty table said the second when it meant the first.

now is unix seconds, passed in rather than read here so the output is deterministic under test.
