feat(editor): add --diff-headers cross-file header comparison Compares two .w* files at the standard catalog header level: 4-byte magic, version, catalog name, entry count, total file bytes. Useful for confirming a JSON round-trip didn't drift, checking whether two preset emissions produced equivalent output, or quickly diagnosing when a content snapshot has silently shifted (entry count up means content was added, file bytes up but everything else same means entry payloads got fatter). Output uses = / ≠ markers per field so visual scanning is fast. Three diagnostic summary cases: identical headers (and same bytes — possibly byte-equal, run cmp(1) to confirm), same shape but bytes differ (entry payloads diverged), and different formats entirely (files are unrelated). Returns exit 1 if any field differs, so the flag composes into shell pipelines (`if diff-headers a.wcms b.wcms; then ...`). World/asset formats stop after magic since their layouts diverge from the standard catalog header. Supports --json variant for tooling integration. 2026-05-09 21:27:26 -07:00			`#pragma once`
