Patch Changes

• Markdown documents containing an astral (non-BMP) codepoint such as an emoji before a guard-unmatched { no longer get a stray { minted into otherwise-untouched text when the document is parsed and re-serialized. Previously, each astral codepoint before the brace shifted an internal protection sentinel one position too far, so on restore a real character was overwritten with { and the genuine { was left unprotected. This affected every editor render, every position: 'replace' agent write, and every disk save of such a document.
