Java record component types are skipped during reference extraction

[oleksii-tumanov]

Context

Java records are emitted as source-backed type nodes, but their component types are skipped during reference extraction. Reproduced on v8 (0.8.51, 73710d3).

Reproducer

class PaymentGateway {}
class Item {}

record Order(PaymentGateway gateway, List<Item> items) {}

Cache result

Label-normalized relevant edges from graphify-out/cache/ast/v0.8.51/<content-hash>.json:

[
  {
    "source": "RecordComponents.java",
    "target": "PaymentGateway",
    "relation": "contains",
    "confidence": "EXTRACTED"
  },
  {
    "source": "RecordComponents.java",
    "target": "Item",
    "relation": "contains",
    "confidence": "EXTRACTED"
  },
  {
    "source": "RecordComponents.java",
    "target": "Order",
    "relation": "contains",
    "confidence": "EXTRACTED"
  }
]

Order has no references to PaymentGateway, List, or Item.

Expected

Emit references edges from Order to PaymentGateway and List with context=field, and to Item with context=generic_arg.

Fixed on v8 (981e2b9, PR #1520, thanks @oleksii-tumanov). Java record component types now emit references edges. Ships in 0.9.1.
