feat: Artisan checklist for application commands, hints and coverage gate

- migrate, migrate:rollback and deferred:purge gain --pretend and --force;
  they and queue:clear confirm only in production on an interactive
  terminal, so deploys over SSH proceed as before
- result lines: Applied N migrations, Rolled back <id> of <plugin>,
  Cleared N jobs from <queue>
- --json for migrate:status, key:generate, route:list, admin:token:create,
  admin:token:list, admin:token:scopes and websockets:health; -q keeps the
  key and the token
- hints for an empty DSN, an unreachable database, an invalid app.key, a
  missing uploads bucket and an application binary run below its root
- flare and websockets:health return bonfire.Reported after printing
- long help and examples for every application command, greeter:hello and
  blog:publish; cmd/summer TestCommandsDocumented fails on any gap

 | Command | Flags | Description |
 |---------|-------|-------------|
 | `serve` | `--addr` (default `:8080`) | Opens the database and uploads bucket, installs cooler (the shared rate-limit store when `http.rate_limit.store` is `redis`), assembles the router, binds the address, starts the in-process job worker (see `queue.work_in_serve`) and serves HTTP until SIGINT or SIGTERM. Once it listens it prints the startup summary on a terminal (unless `-q`), with the admin URL and a warning naming `summer admin:create` when no administrator exists yet, or `off` with the steps to add an admin controller; off a terminal it logs the summary and `listening on <addr>` as records. On a signal it drains requests and the worker within 10 seconds, prints and logs the shutdown report, and exits 0, or 1 when draining fails. |
-| `route:list` | none | Builds the router the same way `serve` does, without opening the database or listening, and prints a table of method, pattern, plugin, middleware and raw flag for every route, followed by the admin status line (`admin: mounted at <prefix>` or `admin: off`). |
+| `route:list` | `--json` | Builds the router the same way `serve` does, without opening the database or listening, and prints a table of method, pattern, plugin, middleware and raw flag for every route, followed by the admin status line (`admin: mounted at <prefix>` or `admin: off`). `--json` prints a JSON array of `method`, `pattern`, `plugin`, `middleware` and `raw` instead. A missing uploads bucket makes `serve` fail with a hint naming `config/storage.yaml`. |
