What changed
Maps classified directive parser failures to stable diagnostics: malformed/duplicate attributes
SNIP013, non-self-closing<Snippet>SNIP014, self-closing<IfVersion>SNIP019, invalid<Else>formsSNIP024, and attributes on closing tagsSNIP011.This PR assigns codes only and does not change parsing or syntax classification.
Why
Syntax diagnostics are separate from successful syntax parsing and from semantic validation diagnostics.
Validation
