Unused build-info vars in internal/cli/root.go

[jadb]

Problem

staticcheck U1000 reports version, commit, date are unused at internal/cli/root.go:31-33.

SetVersion(v,c,d) assigns them and sets RootCmd.Version, but the vars themselves aren't referenced elsewhere.

Fix (recommended)

Remove the stored vars and use RootCmd.Version only:

-  // Build info
-  version string
-  commit  string
-  date    string
 )

 func SetVersion(v, c, d string) {
-  version = v
-  commit = c
-  date = d
   if RootCmd != nil {
     RootCmd.Version = fmt.Sprintf("%s (commit: %s, built: %s)", v, c, d)
   }
 }

Alternative: if the vars are needed later, reference them somewhere (e.g., debug output). But removing them is simplest.
