Subject: [PATCH] fix: flush stdout prompts in first-run config wizard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The prompt_config() function used print!() without flushing stdout,
causing all prompts to be buffered and invisible to the user. The
program appeared to hang silently after 'No config found — first-time
setup'.

Changes:
- Add std::io::stdout().flush().unwrap() after each print!() prompt
- Style prompts with cyan '→' prefix to match CLI conventions
- Show default values in square brackets for relay URL and label
- Use hostname() as default label (was previously Optional/None)
- Add blank line after prompts before '✓ Config saved'
