TL;DR

fixes supabase start and functions serve failing on every restart on Docker Desktop when supabase/functions/.env holds a multiline value

what's missing?

a multiline value such as a quoted PEM key was staged under supabase/.temp/start-secrets and bind mounted into the edge runtime.
stop deletes that folder and the next start recreates it, and Docker Desktop then fails the docker cp of the main service with must be a directory, so only the first start in a project ever worked

now fixed by:

the multiline env script and its values now ride in the same docker cp archive as the main service,
so the edge runtime no longer needs that host folder. a multiline-env folder left by an older CLI is removed on the next start
