[Feature]: static SDK folder

[AielloChan]

Say when I install a new sdk, vfox just create a new folder in temp, then put sdk in it, and update some env.

When I have installed multiple nodejs ( 20.0 and 18.0), I need specify "Which IDE use witch version of nodejs"

For now, folder was ramdonlly named, such as /Users/xxxx/.version-fox/temp/1718035200-58946/nodejs/bin/node, I wish it could be like /Users/xxxx/.version-fox/sdks/nodejs/20.0 and /Users/xxxx/.version-fox/sdks/nodejs/18.0

so that I can easily set IDE a to use version a( just set the sdk path in it), and IDE b use another.
