v21.8.0

* [eas-cli] Add integrations:supabase:connect command

* [eas-cli] Update connect test for provision failure hint

* [eas-cli] Avoid re-run advice after additional Supabase provision

Env-write and missing-credential recovery now print URL/key for manual setup
instead of suggesting another --environment run that would bill a second project.

* [eas-cli] Cover primary provision receipt parse failure in connect

* [eas-cli] Prompt link vs provision after supabase --reauth

Cascade delete clears the EAS project link on reauth; default to
linking an existing project instead of provisioning a new billed one.

* [eas-cli] Cover post-reauth link prompt validation paths

* [eas-cli] Format supabase connect reauth changes

* [eas-cli] Drop redundant URL polyfill and match docs client path

* [eas-cli] Print the Supabase authorize URL before opening the browser

* [eas-cli] Keep the browser open call from rejecting unhandled
