[analyzer] broken renaming of duplicate declarations

[incendial]

Hi,

class SomeClass {
  SomeClass? field;

  SomeClass();
}

class SomeClass {
  SomeClass? field;

  SomeClass();
}

Screen.Recording.2025-09-09.at.21.06.28.mov

Expected behavior:

class SomeClass {
  SomeClass? field;

  SomeClass();
}

class SomeClass1 {
  SomeClass1? field;

  SomeClass1();
}

Dart SDK version: 3.8.1 (stable) (Wed May 28 00:47:25 2025 -0700) on "macos_arm64"

Thanks for the report! Maybe similar problem to #60916, but I'd have to check.

FYI @scheglov @bwilkerson

I'm guessing that the cause is different, but I can't be sure without digging into the code.
