不具合の修正

• Fixed several edge cases in the regular expression implementation, focusing on option mapping, match correctness, and inline flag handling.
• Corrected multiline-related behavior and line-terminator semantics to ensure consistent ^/$ processing and proper newline interpretation (including Unix-lines mode where applicable).
• Addressed a false-positive scenario where an escaped dot ("\.") at the beginning of the input could be misinterpreted as a real "." match, improving prefix-pattern accuracy.
• Fixed support for inline regex flags and aligned them with Java Pattern behavior:
  • i - case-insensitive matching (Pattern.CASE_INSENSITIVE).
  • m - multiline mode for ^/$ anchors (Pattern.MULTILINE).
  • s - dot matches newlines (Pattern.DOTALL).
  • x - whitespace/comments mode (Pattern.COMMENTS).
  • u - Unicode-aware case folding (Pattern.UNICODE_CASE).
  • U - Unicode character classes for \w, \d, \s (Pattern.UNICODE_CHARACTER_CLASS).
• Unsupported flags now fail fast with a clear error, ensuring predictable and standards-aligned regex compilation and matching.
