`save` / `open` / `switch` / `close` / `delete` / `kill-session`, at a glance

These six overlap in what they touch, so here's the full picture in one place:

Command	Touches the live tmux session?	Touches the saved snapshot?
`save`	reads	creates/updates
`open`	creates	reads
`switch`	creates or reads, depending on state	reads
`close`	kills	—
`delete`	—	removes
`kill-session`	kills	removes

close then delete is the deliberate two-step way to fully tear down a session; kill-session is the one-shot shortcut for the same end result.
