Root cause: env.sh skipped sourcing .env when DISINTO_CONTAINER=1,
assuming compose injects all env vars. But cron jobs do NOT inherit
compose env vars — they only get crontab-level variables.
Result: FORGE_TOKEN was empty in every cron poll. API calls returned
nothing, polls silently found "no open PRs" and exited.
Fix: always source .env regardless of DISINTO_CONTAINER. Compose env
vars (FORGE_URL) are set in the crontab env and take precedence.
Entrypoint also adds FORGE_URL to crontab env vars.
