feat: auto-switch to default profile before gateway startup (#734)

When starting gateways, automatically switch to 'default' profile if
current profile is not 'default'. This ensures consistent gateway startup
behavior and prevents port conflicts from different profile configurations.

Changes:
- Check current profile before starting gateways
- Execute 'hermes profile use default' if needed
- Wait 2 seconds for profile switch to take effect
- Update internal GatewayManager state
- Add detailed logging for the switching process
