// handleChdirFlag handles the -C flag before doing anything else.
// The -C flag must be the first flag on the command line, to make it easy to find
// even with commands that have custom flag parsing.
// handleChdirFlag handles the flag by chdir'ing to the directory
// and then removing that flag from the command line entirely.
//
// We have to handle the -C flag this way for two reasons:
//
//  1. Toolchain selection needs to be in the right directory to look for go.mod and go.work.
//
//  2. A toolchain switch later on reinvokes the new go command with the same arguments.
//     The parent toolchain has already done the chdir; the child must not try to do it again.
