/**
 * Output channel extras: colors, hyperlinks, and exit codes without throwing.
 *
 * Demonstrates: the gated `out.color` palette, OSC 8 hyperlinks behind
 * `out.isHyperlinkSupported`, and `out.setExitCode()` for "report and
 * continue" failures.
 *
 * Usage:
 *   npx tsx examples/output-extras.ts
 *   npx tsx examples/output-extras.ts | cat     # colors and links gate off
 *   NO_COLOR=1 npx tsx examples/output-extras.ts
 *   npx tsx examples/output-extras.ts; echo "exit: $?"
