Refactor chained .replace() to single-pass tokenizers in pattern matching:
- matchConfigPattern in config-matchers.ts and index.ts
- escapeHeaderSource (new) replaces inline chained escaping in matchHeaders/applyHeaders
- matchMiddlewarePattern in prod server entry template
- matchPattern in middleware.ts
Also:
- escapeHeaderSource correctly handles :param(constraint) patterns
- Fix decodeURIComponent parity gap in index.ts matchConfigPattern
- Fix redundant dot in middleware.ts tokenizer char class
- Add lgtm suppression comments for false positives in test files
- Add unit tests for escapeHeaderSource
