/**
* The compose-era local database convention (`bos dev` provisioned Postgres
* via the committed docker-compose.yml): every `*_DATABASE_URL` pointed at
* `postgres://everythingdev:everythingdev@localhost:<port>/<db>` on the
* hardcoded 5432–5435 block. Those are exactly the opt-ins that made two
* concurrent local projects fight over host ports.
*
* The compose-era convention is retired — local persistence is a
* file-backed PGlite data dir (`.bos/db`), tests run on in-memory pglite.
* `bos dev` repairs leftover state once, idempotently:
*   1. `.env` lines whose URL matches the conventional shape (user, host,
*      and database name — port too, but drift ports like 5532 from the old
*      +100 allocator also match by name) are rewritten to the new defaults.
*      Any other `postgres://` URL is operator-owned and left alone.
*   2. A leftover scaffold-shaped `docker-compose.yml` is moved to
*      `.bos/compose-retired/` rather than deleted; operator-authored
*      compose files (different service names/images) are untouched.
