fix(software): pass winget exe path into background jobs, add exit 3010 as OK

Background jobs do not reliably inherit PATH from the parent session,
causing winget calls to fail silently. Now the resolved executable path
is passed explicitly as an argument into each Start-Job scriptblock.
Also treats exit code 3010 (success + reboot required) as OK.
