fix(wpcarro/emacs): Debug vterm-mgt.el

TL;DR:
- vterm-mgt-repopulate-cycle -> vterm-mgt-reconcile-state
- call vterm-mgt-reconcile-state everywhere to ensure state is consistent
- prevent vterm from swalling EXWM KBD (C-S-f)
- support vterm-mgt-select
- prevent type error in cycle-append
- pass t to (vterm t) to ensure it isn't a find-or-create
