Subject: [PATCH] fix(wix): split ProgID per extension to avoid duplicate Verb
 registry key

A single ProgID with two `<Extension>` children, each carrying its own
`<Verb Id='open'>`, makes WiX emit two rows with the same Registry
primary key and light fails with LGHT0130. Split into one ProgID per
extension (`OpenCADStudio.DWG`, `OpenCADStudio.DXF`); both still invoke
the same exe with the file as `argv[1]`.
