chore(deps): drop mitchellh/go-homedir for stdlib os.UserHomeDir

mitchellh/go-homedir is archived upstream. Its homedir.Dir() is
effectively equivalent to os.UserHomeDir() (stdlib since Go 1.12) on
Linux/macOS/Windows. The only practical behavioral delta is on Unix
with HOME unset: go-homedir falls back to /etc/passwd via os/user;
stdlib returns an error instead. That path already log.Fatals with the
error, so the user-visible outcome is equivalent.

Also evaluated blang/semver v3 -> v4 in this pass but reverted: the
v3 import path is pinned transitively by rhysd/go-github-selfupdate
(selfupdate.Release.Version is blang/semver v3). A clean v4 migration
requires first replacing the selfupdate library.
