Add salemsayed/codexbar-meter (#243)

A bar widget and attached panel showing AI provider usage limits reported
by the local CodexBar CLI. The bar keeps a configurable number of provider
meters; the panel lists every provider, quota window, credit balance, and
pace summary, and scrolls when the response is taller than the panel.
