Alexander Whitestone 48819eb36d feat: tower session — persistent Hermes ↔ Timmy conversation loop
Two-pane tmux session with file-based message passing:
- tower-hermes.sh: Hermes side (cloud/Claude)
- tower-timmy.sh: Timmy side (HERMES_HOME=~/.timmy)
- tower-watchdog.sh: self-healing, restarts dead panes
- tower-session.sh: tmux bootstrap script

Communication via ~/.tower/*.msg files.
Both agents maintain named sessions (tower-hermes, tower-timmy)
for conversation continuity across restarts.
