Pantheon Release Adds Command Palette and Status Bar

@witcheer posted that the Pantheon release included terminal upgrades. One change lets users press Ctrl+P to open a command palette where slash commands become searchable by typing. Another update makes the status bar display live cache-hit rate and tokens per second. The post notes that cache hits represent turns users pay less for. The message cuts off mid-sentence after that observation. No other details about the release appear in the supplied source line.
