fix(zsh): detect relative paths through symlinks as directories

When cwd is a symlink, [[ -d ../foo ]] follows the symlink before
resolving .., so the check fails even though cd ../foo would succeed
via the shell's logical path tracking. Allow paths containing ..
through to __zoxide_cd, which relies on the shell's native cd behavior.

Fixes #1166
