/**
 * /pi slash command and its Block Kit control panel.
 *
 * Slack has no per-command autocomplete or typed subcommands, so a single
 * global /pi command carries text subcommands:
 *   status | model <ref> | models | reset-model | thinking <level> | new | stop
 * A bare `/pi` opens an interactive panel (model/thinking pickers, new-session
 * and stop buttons) instead of a text usage dump; `/pi help` prints the text
 * usage. Replies are ephemeral (respond() posts to the response_url).
