fix(core): keep CRLF notes intact — frontmatter detection and line endings (T4.1, #3)

readVoiceFields/patchFrontmatter split on \r?\n; patchFrontmatter and renderNote write in the note's own line-ending style. Before: a CRLF note's '---\r' was not recognised, the patch prepended a second frontmatter block and the record fell out of the queue.
