Replace sanitizeForInlineCode with CommonMark-compliant markdownInlineCode

- markdownInlineCode() uses a fence length = maxRun+1 per CommonMark spec,
  preserving the original string (no information loss from backtick→apostrophe)
- Normalises CR/CRLF to LF before wrapping (inline spans can't span lines)
- Export markdownInlineCode for testability
- Add 6 unit tests for markdownInlineCode (plain text, single/double backtick,
  CRLF normalisation, backtick-only values)
- Add regression test for formatValidationError with backtick in received value
- Add regression test for resolvePromptFilePath warning with backtick in path
