Benjamin Admin c09838e91c Fix spine shadow false positives: require dark valley, brightness rise, trim convolution edges ...

The _detect_spine_shadow function was triggering on normal text content
because shadow_range > 20 was too low and convolution edge artifacts
created artificially low values. Now requires: range > 40, darkest < 180,
narrow valley (not text plateau), and brightness rise toward page content.
