v1.03 - First-Run Setup Dialog

Changes

• First-run setup dialog: When no settings file exists, a GUI dialog now prompts for API keys instead of crashing
• API key whitespace fix (from v1.02): Keys are stripped of leading/trailing spaces
• Settings are saved automatically to nonkyc_settings.json next to the exe
• Show/hide toggle for secret key

Download

• mewc_trader.exe - Windows executable (standalone, no Python required)
• Just download and run - it will ask for your API keys on first launch
