Function load_context_runs 

pub fn load_context_runs(
    root: &Path,
    suite: &str,
) -> (Vec<EconomicsContextRun>, Vec<String>)

Every context measurement recorded under root for suite, oldest first.

The order is by measured_at, then commit, never by file name, so the last entry is the measurement the summary reports. A record under another schema is named in the second list rather than read as if it were this one.
