Claude a55f8e2d85 fix(kyber-linux): fix prefix path — use numeric appid so Steam finds it
Steam sets STEAM_COMPAT_DATA_PATH to compatdata/<appid> when launching
a non-Steam shortcut. The prefix was named 'kyber' so Steam was launching
into an empty prefix, causing immediate exit. Change KYBER_COMPAT_ID to
match KYBER_APPID (9900000001) and migrate any existing 'kyber' prefix.

Also handle cmd.exe being a symlink: resolve and copy the real file as
cmd-real.exe, then remove the symlink before writing the shim so we only
affect the Kyber prefix and not Proton globally.
