cat: 1.2.0 — click popup panel with the cat and CPU % (#103)

Clicking the bar widget now toggles an attached panel showing the same
cat glyph at panel size plus the CPU percentage, replacing the old
notification. The widget publishes its visible state (glyph, cpu,
color, pace) through the plugin's shared state store and the panel
re-renders on each update, keeping the big cat frame-synced with the
bar cat.
