Show banner only for help in TTY

Avoid building the ASCII/banner art unless help is being requested: parse_args now detects -h/--help and only constructs the help description in that case. At startup, the banner is printed (not logged) only when stdout is a TTY and the terminal is wide enough; failures while building/printing the banner are caught to keep startup robust. Also removed dlclivegui/assets/* from the coverage omit list so those files will be considered by coverage tooling.
