Subject: [PATCH] test: red for register's stray-store creation outside a
 project (refs #305)

register_process/register_campaign call env.registry() without the
no-project guard their show/runs siblings carry, so Env::runs_root()'s
relative fallback silently creates ./runs/ in an innocent cwd and
registers the document there (exit 0). The E2E test pins both verbs and
both halves of the wanted refusal: exit 1 naming the missing Aura.toml,
and no store directory created as a side effect.
