feat(cli): color-coded help matching typer's Rich styling

Options use typer's color scheme: bold cyan for long flags, bold green
for short flags, bold yellow for metavar (TEXT). Commands use cyan for
group name and bold for verb, giving a visual indication that they're
tied together. Top-level commands (download, infer, search) are just
bold.

374 tests pass, all linting clean.
