This CL also fixes EOS handling to account for not-yet-copied samples in `remainingInputToCopyFrameCount`, which would throw off the final output sample count calculation. For testing, we allow a tolerance of 0.000017% drift between expected and actual number of output samples. The value was obtained from running 100 iterations of `timeStretching_returnsExpectedNumberOfSamples()` and calculating the average delta percentage between expected and actual number of output samples. Roughly, this means a tolerance of 40 samples on a 90 min mono stream @48KHz. PiperOrigin-RevId: 683133461
