1b549962b2 Fix panic on negative slice indices that underflow after adjustment
sliceArrayOperator adjusts negative indices by adding Content length,
but does not clamp the result. When the absolute value of a negative
index exceeds Content length (e.g. .[-99999:3] on a 3-element array),
the adjusted index remains negative and causes an out-of-bounds access
in the Content slice loop.

Extract the adjust-and-clamp logic into clampSliceIndex and use it for
both index positions.

Reproducer (panics before this fix, returns full array after):

    echo '[a, b, c]' | yq '.[-99999:3]'

Generic ast (#1829)
