atproto_sdl/parser

Recursive-descent parser over the lexer’s token stream: the document header (@description/@revision directives) and top-level items. Type/field/param parsing lives in parser/types, ref paths and attributes in parser/values, and raw token-stream primitives in parser/cursor. The grammar is deliberately uniform and permissive: position restrictions the target AST enforces turn into Semantic errors in lower, not here. Field and parameter lists accept a trailing comma OR no separator at all (newline-only), so hand-written SDL isn’t forced into one style.
