Render a lowercase ktx half-block wordmark with the brand-orange gradient above the `ktx setup` intro on interactive TTYs. The banner degrades through truecolor, xterm-256, and monochrome, and is skipped on non-TTY, non-Unicode, or too-narrow terminals. Extract shared color/Unicode capability detection into io helpers (shouldUseColorOutput, colorDepthForOutput, unicodeSupported) so the banner and doctor report route through one implementation.
