pub fn project_motion_context(
ctx: &MotionContext<'_>,
) -> Result<MotionContext, String>Expand description
Project a live MotionContext into its owned WIT
mirror (host→guest). Reads only the owned scalars — &Buffer,
&CancellationToken, and the tree-sitter scope_resolver are host-owned and
reached (if at all) through the document handle, never this record.
