/**
* Finds the best locale match using a three-tier optimization hierarchy.
*
* ## Three-Tier Matching Algorithm:
*
* **Tier 1 - Fast Path** (O(n)): Exact string matching via Set lookup
* - Example: 'en' matches 'en' exactly → distance 0
* - Solves #4936: 48x faster than baseline (12ms vs 610ms with 700+ locales)
*
* **Tier 2 - Fallback Path** (O(k×n)): Maximization + progressive subtag removal
* - Maximizes requested locale, then removes subtags right-to-left
* - Example: "zh-TW" → "zh-Hant-TW" → ["zh-Hant-TW", "zh-Hant", "zh"]
* - Distance: 0 for maximized match, 10 per removed subtag + position penalty
* - 40-50x faster than full UTS #35, handles 99% of real-world cases correctly
*
* **Tier 3 - Slow Path** (O(n×m), memoized): Full UTS #35 CLDR matching
* - Calculates Language-Script-Region distances using CLDR data
* - Handles complex cases like cross-script matching (sr-Cyrl ↔ sr-Latn)
* - Only used when Tiers 1 & 2 find no match
* - Still 6x faster than baseline due to memoization
*
* ## Performance Impact of Maximization:
*
* While Tier 2 now calls `Intl.Locale().maximize()` once per requested locale,
* this is still much faster than Tier 3's full distance calculation:
* - Tier 1: ~12ms (exact match, no maximization)
* - Tier 2: ~13-15ms (maximization + fallback)
* - Tier 3: ~100ms+ (full UTS #35 with all supported locales)
*
* @param requestedLocales - Locale identifiers in preference order
* @param supportedLocales - Available locale identifiers
* @param threshold - Maximum distance (default: 838, from CLDR)
* @returns Matching result with distances
*
* @example
* ```ts
* // Tier 1: Exact match
* findBestMatch(['en'], ['en', 'fr'])
* // → { matchedSupportedLocale: 'en', distances: { en: { en: 0 } } }
*
* // Tier 2: Fallback with maximization
* findBestMatch(['zh-TW'], ['zh-Hant'])
* // → zh-TW maximizes to zh-Hant-TW, falls back to zh-Hant (distance 0)
*
* findBestMatch(['en-US'], ['en'])
* // → en-US maximizes to en-Latn-US, falls back to en (distance 10)
*
* // Tier 3: Full calculation
* findBestMatch(['en-XZ'], ['ja', 'ko'])
* // → No fallback match, uses UTS #35 to find closest match
* ```
