feat(run): show runs like gh, watch them live, and download artifacts

run list prints a table with a status icon, the workflow name, title,
branch, event, elapsed time and age, and the total from the server; runs
carry workflow, workflow_path and run_number in JSON. run view shows the
run's state and trigger, its jobs with their steps and durations, the
next steps and the run's URL; --json includes the jobs, --log prints
their logs and --web opens the run.

Run commands accept #N and run URLs, and ask for a recent run in a
terminal when the argument is left out. run watch redraws the run on the
alternate screen, then prints it with a summary; an expired --timeout
names the run and suspects a missing runner when no job started.

run cancel no longer asks for confirmation, rerun refuses unfinished runs
up front, reruns a single job with --job and reports the new attempt,
and delete names the run in its prompt. run logs follows several jobs
with --follow, prefixing lines with the job's name, selects jobs by name
or with --failed, and downloads the archive with --output or --dir.
run download extracts the artifacts of a run by name, and artifact list
shows sizes and expiry.
