fix(cli): handle standalone short options like -f that take values

When a global short option like -f (for --format) appears after a subcommand
as a standalone token (e.g., 'agents info -f json'), it was not being promoted
because the code only handled fused forms like '-fjson'.

This fix adds a check for standalone short options in _GLOBAL_VALUE_SHORT_OPTIONS
that consume the following argument, allowing 'agents info -f json' to work
correctly in addition to 'agents info -fjson'.
