PlaybackRate.displayText/compactDisplayText used String(format: "%.2gx"), whose significant-figure notation dropped meaningful digits (1.25 -> "1.2x") and rounded others (1.75 -> "1.8x"). Replace with a fixed two-decimal format + trailing-zero strip so whole rates have no decimal (2 -> "2x"), halves show one (1.5 -> "1.5x"), and quarter-steps are preserved (1.25 -> "1.25x"). Adds a Swift Testing suite (PlaybackRateTests) proving red->green.
