* Optimize PipeTable parsing: O(n²) → O(n) for large tables
Pipe tables were creating deeply nested tree structures where each pipe
delimiter contained all subsequent content as children, causing O(n²)
traversal complexity for n cells. This change restructures the parser to
use a flat sibling-based structure, treating tables as matrices rather
than nested trees.
Key changes:
- Set IsClosed=true on PipeTableDelimiterInline to prevent nesting
- Add PromoteNestedPipesToRootLevel() to flatten pipes nested in emphasis
- Update cell boundary detection to use sibling traversal
- Move EmphasisInlineParser before PipeTableParser in processing order
- Fix EmphasisInlineParser to continue past IsClosed delimiters
- Add ContainsParentOrSiblingOfType<T>() helper for flat structure detection

Tables with 5000+ rows previously crashed due to stack overflow from
recursive depth. They now parse successfully with linear time complexity.

* feat(link-helper): improve ASCII normalization handling
Enhanced the `Urilize` method to better handle ASCII normalization and special characters. Added support for decomposing characters when `allowOnlyAscii` is true and skipping diacritical marks. Introduced handling for special German, Scandinavian, and Icelandic characters via new helper methods: `IsSpecialScandinavianOrGermanChar` and `NormalizeScandinavianOrGermanChar`.
Reorganized `using` directives for better clarity. Updated the processing loop in `Urilize` to handle normalized spans and ASCII equivalents more effectively. These changes improve link generation compatibility across various languages.
* Add tests for Scandinavian and German character normalization
Added tests for NormalizeScandinavianOrGermanChar method to validate character normalization for various special characters in both ASCII and non-ASCII contexts.
* test(link-helper): update ASCII transliteration tests
Updated test cases in `TestUrilizeOnlyAscii_Simple` to reflect
changes in `LinkHelper.Urilize` behavior. Non-ASCII characters
like `æ` and `ø` are now transliterated to their ASCII
equivalents (`ae` and `oe`) instead of being removed.
