tools.zsh: add tmux session chooser for SSH connections
When SSHing into a machine with existing tmux sessions, show an fzf
picker instead of always creating a new session. The picker shows
session name, window count, creation time, and attach status.
- Preview pane shows the current content of each session (via capture-pane)
- DEL key kills the highlighted session and refreshes the list
- Selecting a session attaches to it
- Selecting '>>> new session <<<' or pressing ESC creates a new one
- Local terminals are unaffected, only triggers when SSH_CLIENT is set
