### Issue The `--with-default-root-credentials` flag only works on first server start. (when no `local_data` directory exists) On subsequent starts, the flag is ignored but the server still logs: ``` INFO iggy_server: Using default root credentials (username: iggy, password: iggy) - FOR DEVELOPMENT ONLY! ``` This misleads users into thinking the credentials are active when they're not. This also affects users who manually set `IGGY_ROOT_USERNAME` and `IGGY_ROOT_PASSWORD` environment variables after the server has already created a root user. ### Steps to Reproduce ```bash # First run - creates root user with random password cargo run --bin iggy-server # Stop and restart with flag cargo run --bin iggy-server -- --with-default-root-credentials # Authentication fails cargo run --example getting-started-producer ``` ### Root Cause The flag sets `IGGY_ROOT_USERNAME=iggy` and `IGGY_ROOT_PASSWORD=iggy` environment variables, but `load_users()` in `core/server/src/streaming/systems/users.rs` only creates a new root user when `users.is_empty()`. Since `local_data` already contains the user from the first run, the flag is silently ignored. ### Proposed Fix - Add warning log when flag/environment variables are used but users already exist - Add information in README that existing user data persists across restarts - Update CLI help text to clarify this behavior -- This is an automated message from the Apache Git Service.
