fix(web): 18 multi-language CSV tables, RFC 4180 escaping, schema sync

- Generate CSVs for Struct, Enum, Macro, Trait, Impl, TypeAlias, Const,
  Static, Property, Record, Delegate, Annotation, Constructor, Template,
  Module, Namespace, Union, Typedef (were defined in schema but silently
  dropped during CSV generation — non-JS/TS repos lost all nodes)
- Escape community keywords array in CSV to prevent comma breakage
- Add Section to NodeLabel type, NODE_COLORS, NODE_SIZES
- Add 7 missing REL_TYPES: HAS_METHOD, HAS_PROPERTY, OVERRIDES, ACCESSES,
  INHERITS, USES, DECORATES
- RFC 4180 doubled-quote regex for relation CSV parsing
