Compute the axis-aligned bounding box of a set of 2D coordinates.
Input: flat Float64Array of [lng0, lat0, lng1, lat1, ...].
Output: Float64Array of [minLng, minLat, maxLng, maxLat].
Uses a manual 4-wide f64 comparison pattern for efficient vectorization
hints to the LLVM backend (effectively SIMD-style without explicit SIMD intrinsics).
