/**
* Sidebar Order Validator
*
* Validates sidebar.order values in YAML frontmatter of markdown doc files.
*
* What it checks (English — strict, errors):
* - Duplicate sidebar.order values within the same directory
* - Gaps in the ordering sequence (e.g., 1, 2, 4 missing 3)
* - sidebar: block present but missing order: field
*
* What it checks (translations — errors + warnings):
* - Same structural rules as English (duplicates, gaps) — errors
* - Order drift from English counterpart — warnings (non-blocking)
*
* Usage:
* node tools/validate-sidebar-order.js
