Nit: wrap the commit message at around 70 columns rather than 45 or so.

This constructs the command as "git symbolic-ref HEAD <ref> --quiet".
Although that's not wrong per-se, it does perhaps set an undesirable
precedent. A more standard construction would be:

    argv_array_push(..., "symbolic-ref");
    if (opts->quiet)
        argv_array_push(..., "--quiet");
    argv_array_pushl(..., "HEAD", symref.buf, NULL);

I used "pushl" on the last one to indicate the semantic relationship
between those two arguments.

Nit: the above code is directly related to the code just below, so the
new blank line you add here somewhat (undesirably) divorces the pieces
of code from each other

I could also see this one re-written as:

    argv_array_push(...,"reset");
    argv_array_push(...,"--hard");
    if (opts->quiet)
        argv_array_push(...,"--quiet");

now that the command invocation has added another option.

Not at all worth a re-roll.

This test is going to create the new worktree directly in Git's t/
directory due to "../foo". Please don't do that. Use a name without
the leading "../".

Also, you should make sure that the worktree doesn't already exist
(wasn't created by an earlier test), otherwise the "git worktree add"
command will fail. So, either choose a distinct worktree name or use
"test_might_fail git worktree remove -f <worktree>" before the "git
worktree add" command.
