Summary
Implements a versioned Rust-owned mdast provenance contract for deterministic editor bridges. Rust attaches

MdiMdastProvenanceprovides version, Rust IR construct path/type, original UTF-8 span, zero or more canonical projection targets (block index, blockText/annotation channel, grapheme range and annotation index), pluscontainer | textBearingandsourceBacked | synthetic | unmapped. It is transient mdast data and does not affect canonical MDI, Markdown, HTML, clipboard, or persisted semantics.Downstream use
