Render /list-claude-pr-status output as a markdown table (#1437)

The command previously left table rendering to the assistant. Move
formatting into the script itself so output is a complete, ready-to-show
markdown table with clickable PR links, READY rows first then RUNNING.
Add an explicit fallback message for the empty-result case.

Verified locally against current open claude/* PRs and against an empty
TSV before opening the PR.
