Markdown parsing fails on Windows (CRLF) and slugify doesn't support non-Latin characters

[baslie]

Problem

Product roadmap data from product-roadmap.md doesn't display on the site — shows "No roadmap defined yet" EmptyState even when the file contains valid content.

Root Causes

1. Windows CRLF line endings break regex matching

The regex patterns in markdown parsers use \n for line breaks, but files saved on Windows use \r\n:

// product-loader.ts:126
const sectionMatches = [...md.matchAll(/### (\d+)\.\s*(.+)\n+([\s\S]*?)(?=\n### |\n## |\n#[^#]|$)/g)]

This pattern fails to match sections when the file has CRLF line endings.

2. slugify() doesn't support Cyrillic (and other non-Latin) characters

// product-loader.ts:28-34
function slugify(str: string): string {
  return str
    .toLowerCase()
    .replace(/\s+&\s+/g, '-and-')
    .replace(/[^a-z0-9]+/g, '-')  // ← Removes ALL non-Latin characters!
    .replace(/(^-|-$)/g, '')
}

For Cyrillic input like "Главная страница", this returns an empty string "", breaking section IDs and routing.

Affected Files

• src/lib/product-loader.ts — parseProductOverview, parseProductRoadmap, slugify
• src/lib/data-model-loader.ts — parseDataModel
• src/lib/shell-loader.ts — parseShellSpec
• src/lib/section-loader.ts — parseSpec

Proposed Solution

1. Normalize line endings before parsing

function normalizeLineEndings(text: string): string {
  return text.replace(/\r\n/g, '\n').replace(/\r/g, '\n')
}

Add md = normalizeLineEndings(md) at the start of each parse function.

2. Add transliteration to slugify()

const cyrillicToLatin = {
  'а': 'a', 'б': 'b', 'в': 'v', 'г': 'g', 'д': 'd',
  'е': 'e', 'ё': 'yo', 'ж': 'zh', 'з': 'z', 'и': 'i',
  // ... full map
}

function transliterate(str: string): string {
  return str.split('').map(char => {
    const lower = char.toLowerCase()
    return cyrillicToLatin[lower] ?? char
  }).join('')
}

function slugify(str: string): string {
  return transliterate(str)
    .toLowerCase()
    .replace(/\s+&\s+/g, '-and-')
    .replace(/[^a-z0-9]+/g, '-')
    .replace(/(^-|-$)/g, '')
}

Expected Results

Input	Output
"Главная страница"	glavnaya-stranitsa
"Каталог проектов"	katalog-proektov
"Invoice Management"	invoice-management
