Add Openbox pipe menu renderer

render/1 turns a list of #desktop_entry{} into the XML Openbox expects
on stdout from a pipe menu: hidden entries dropped, remaining ones
sorted case-insensitively by name, each as an <item> wrapping an
Execute action with its command and (if present) icon attribute.
XML-escapes label/command/icon values.

Icon values are passed through as-is (theme icon names, not resolved
paths) -- icon theme resolution is left for later, separate from
rendering. Service wiring (scan -> parse -> render, with caching and
invalidation) is also left for later.
