Add a lightweight hook that runs on session start to check if any
API keys are configured. Warns users if no config is found and
checks file permissions on existing config files.
Checks (in order): .claude/last30days.env, ~/.config/last30days/.env,
OPENAI_API_KEY env var, SCRAPECREATORS_API_KEY env var.
