feat(aix): add windows to existing session, fix special char handling

Allow calling aix from within the ai tmux session to add new project
windows. Already-open projects are filtered from the selection list.
Use tmux window IDs instead of names to fix errors with dots in
directory names (e.g. chime.el).
