Catppuccin renders #T, the pane title, in the window list. Any program in the
pane can overwrite that with an OSC escape -- the shell writes the hostname and
Claude Code writes its current task -- so a window renamed with prefix+, never
appeared anywhere.
The status bar now shows the window name, falling back to the pane title while a
window holds a single pane. Once a window is split, pane titles appear on the
pane borders instead; pane-border-status takes no format, so a
window-layout-changed hook recomputes it on both split and close. Adds a binding
for select-pane -T, which has no default.
