Module reader 

SegmentReader — zero-copy view over segment bytes.

Designed to wrap an mmap’d file in production. The reader only borrows the slice and lazily decodes tile payloads on demand; the footer is decoded eagerly at construction so subsequent tile lookups are bounded reads + zerompk decode (no rescan).
