CLI: Inspect Results

R is --repo OWNER/NAME, or another scope.

Command	Does
`results R`	Pass rate and cost per configuration, and every task, hardest first
`task results RUN_ID TASK_ID R`	Every configuration on one task, with failure explanations and the fairness verdict
`task explain RUN_ID TASK_ID R [--config KEY] [--model M --credential ID] [--wait]`	Explain a task’s unexplained failures
`task audit RUN_ID TASK_ID R --model M --credential ID [--wait]`	Judge whether the task is `fair`, `unfair`, or `unclear`
`summaries R`	The latest Model Summaries report
`summaries create R --model M --credential ID [--config KEY ...] [--wait]`	Summarize how configurations differ

task explain uses a managed model where the deployment offers one. Audits and summaries need a saved model API key.
