Kotlin extractor: scope Object-method redeclaration recovery

Why this is needed:
- library-tests/java-kotlin-collection-type-generic-methods/test.ql regressed with extra equals(Object) rows on generic collection/map/list declaration variants.
- At the same time, java-interface-redeclares-tostring must still recover Object-method redeclarations for Java binary interfaces under K2.

What changed:
- In K2 ASM probing, treat classes with kotlin.Metadata as non-Java binaries for javaBinaryDeclaresMethod, so Java-redeclaration recovery does not fire on Kotlin binary classes.
- Keep equals(Object) K2 Any/Any? compatibility handling, but constrain the workaround to non-generic parent classes and skip it when a concrete sibling declaration already exists.
- Preserve the existing toString/hashCode redeclaration recovery path for affected Java binaries.

Effect:
- Removes the spurious equals(Object) rows in java-kotlin-collection-type-generic-methods while retaining expected Object-method extraction in java-interface-redeclares-tostring.

+## 7.0.0
+
+### Breaking Changes
+
+* Renamed types related to *operation* expressions. The QL classes `BinaryArithmeticOperation`, `BinaryBitwiseOperation`, and `BinaryLogicalOperation` now include compound assignments; for example, `BinaryArithmeticOperation` now includes `a += b`.
+
+### Major Analysis Improvements
+
+* Added Razor Page handler method parameters (e.g., `OnGet`, `OnPost`, `OnPostAsync`) as remote flow sources, enabling security queries such as `cs/sql-injection` to detect vulnerabilities in `PageModel` subclasses.
+
+### Minor Analysis Improvements
+
+* Improved property and indexer call target resolution for partially overridden properties and indexers.
+* Improved extraction of range-access expressions on spans and strings (for example, `a[0..3]`). These expressions are now extracted as `Slice` (span) or `Substring` (string) calls.
+* Improved call target resolution for ref-return properties and indexers.

+## 7.0.0
+
+### Breaking Changes
+
+* Renamed types related to *operation* expressions. The QL classes `BinaryArithmeticOperation`, `BinaryBitwiseOperation`, and `BinaryLogicalOperation` now include compound assignments; for example, `BinaryArithmeticOperation` now includes `a += b`.
+
+### Major Analysis Improvements
+
+* Added Razor Page handler method parameters (e.g., `OnGet`, `OnPost`, `OnPostAsync`) as remote flow sources, enabling security queries such as `cs/sql-injection` to detect vulnerabilities in `PageModel` subclasses.
+
+### Minor Analysis Improvements
+
+* Improved property and indexer call target resolution for partially overridden properties and indexers.
+* Improved extraction of range-access expressions on spans and strings (for example, `a[0..3]`). These expressions are now extracted as `Slice` (span) or `Substring` (string) calls.
+* Improved call target resolution for ref-return properties and indexers.

+  variants, and `Log`/`LogAttrs`) are now recognized as logging sinks, so the

+* `DataFlow::ResultNode`s are no longer created for returned expressions in functions with named result parameters. In this case there are already result nodes corresponding to `IR::ReadResultInstruction`s at the end of the function body.
+* `FuncTypeExpr.getNumResult()` now gets the number of result parameters. It previously got the number of result declarations, which is different when one result declaration declares more than one variable, as in `x, y int`. All uses of it expected the number of result parameters. Its QLDoc has been updated.
