`lore test` is not setting `LORE_ENV=test` properly

`lore test` should set `LORE_ENV=test`. Looks like it is being set too late and the test config is not being used.

Start at the implementation of the `lore test` command and trace when `LORE_ENV` is assigned relative to test configuration loading. Verify that running `lore test` sets `LORE_ENV=test` early enough for the test configuration to be used, then run the command's existing tests or a focused reproduction to confirm the behavior.
