Fix CLI logo wrapping in help output

[Raviguntakala]

Description

The CLI logo in opencode --help is currently distorted due to hardcoded text wrapping at 100 characters.
Proposed Fix: Disable wrapping (.wrap(null)) in yargs configuration to allow the ASCII art to render correctly on all terminal sizes.
