Eugene Petrenko 60bf256345 Reject non-positive @PPI hints ... Codex review flagged that a mistyped "@0" or "@-1" parsed to a non-nil ppi that persisted and was fed straight into VZMacGraphicsDisplayConfiguration, bypassing the 72 fallback and risking a display that fails to build until the user manually resets it. Guard both ends: the --display parser now keeps only a positive PPI (zero/negative ignored just like non-numeric input), and effectivePixelsPerInch treats a non-positive stored value (e.g. from a hand-edited config) as unset, falling back to 72.
