fix: state standalone versions from their code

Each standalone profile records where its version is read: the source
at its pin (clk 2026-07-23-136-g9020107, shadps4 0.20.1 WIP, eden
v0.2.0-401-g26a03d2), the APK, binary or archive read (kind package),
or, where no reading can be made, kind unverified with the reason: a
host the tools cannot read, a forge gone or not answering, no build
recorded as read, a pin on another branch. Those keep their value,
unconfirmed.
