audit m7 ranked this medium because "every caller inherits the opaque click". there
are no callers. nothing has imported Combobox since the initial commit, there is no
barrel that re-exports it, and nothing anywhere sets `href` on a SelectOption — so the
navigate, the separator that only appeared for href options, and the href field on both
declarations of the type were all unreachable.
writing anchor semantics into a component that is never rendered is building, not
fixing. the Command primitives it used stay; AIHarnessesSection needs them.
