ensure_env_loaded() set _env_loaded before _load_dotenv() ran. With F2,
load_env_or_report() turns the EnvFileError into a return value, so a second
main() in the same process skipped the unreadable file and ran unconfigured
(codex R1: registry.main twice -> rc 1 then rc 0 with a job registered; a
repaired file was never read). The flag is now set only after a successful
load: a failure is retried on the next call, a success still loads once.
envfile parses the whole file before applying, so a failed load sets nothing.
MESSAGING.md: the one-line ERROR is the Python entry points'; the wrapper
adds its own "ERROR: cannot load <path>" line (codex, minor).
Test: in one process, registry.main twice on an undecodable file is rc 1
both times, prints the ERROR line twice and registers nothing; the repaired
file is applied on the next call; a later change is not re-read. At 95eabc6
it fails with rc [1, 0], one job registered and the value unset.
