CI inherits DATABASE_URL from the outer shell (capakraken_test URL).
loadWorkspaceEnv uses dotenv semantics — pre-existing process.env wins
over .env file contents — so the first test's assertion
'DATABASE_URL === postgres://from-env' failed only in CI. Moving
clearEnv into beforeEach makes the test order-independent and
immune to inherited env. Reproduced by running the suite locally
with DATABASE_URL exported.
