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.

-without validation, allowing an attacker to manipulate the AI's behavior.</p>
-<sample src="examples/prompt-injection.py" />
-<p>One way to fix this is to provide the user-controlled value in a message with the "user" role,

-<qhelp>
-
-<overview>
-<p>If untrusted input is included in a user-role prompt sent to an AI model, an attacker can inject
-instructions that manipulate the model's behavior. This is known as <i>indirect prompt injection</i>
-when the malicious content arrives through data the model processes, or <i>direct prompt injection</i>
-when the attacker controls the prompt directly.</p>
-
-<p>Unlike system prompt injection, user prompt injection targets the user-role messages. Although
-user messages are expected to carry user input, passing unsanitized data directly into structured
-prompt templates can still allow an attacker to override intended instructions, extract sensitive
-context, or trigger unintended tool calls.</p>
-</overview>
-
-<recommendation>
-<p>To mitigate user prompt injection:</p>
-<ul>
-<li>Ensure that all data flowing into user input is intended and necessary for the purpose of the AI system.</li>
-<li>Ensure the system prompt clearly describes the purpose, scope and boundaries of the AI system. Instruct the system to deny input that falls outside these boundaries.</li>
-<li>If creating a prompt out of multiple user-controlled values, assume that each of them can be malicious. Ensure the range of possible values is restricted and validated.
-For example, if a prompt includes a question and the intended language to respond in, validate that the language is one of the supported options.</li>
-<li>Consider using guardrails on the input like the OpenAI guardrails library to enforce constraints and prevent malicious content from being processed.</li>
-<li>Apply output filtering to detect and block responses that indicate prompt injection attempts.</li>
-</ul>
-</recommendation>
-
-<example>
-<p>In the following example, user-controlled data is inserted directly into a user-role prompt
-without any validation, allowing an attacker to inject arbitrary instructions.</p>
-<sample src="examples/user-prompt-injection.py" />
-
-<p>The following example applies multiple mitigations together, and only includes data that is
-necessary for the task in the prompt: the value that selects behavior (the response language) is
-validated against a fixed allowlist before it is used, and the system prompt clearly describes the
-assistant's scope and instructs it to ignore embedded instructions.</p>

-* Replaced the experimental `py/prompt-injection` query with two new queries, `py/system-prompt-injection` and `py/user-prompt-injection`, to distinguish untrusted data flowing into system-level prompts and tool descriptions from data flowing into user-role prompts. The queries model the `openai`, `agents`, `anthropic`, `google-genai`, `openrouter` and `langchain` frameworks.

 ```
 
-Inside `rule!`, captures are Rust variables, so `{name}` inserts a
-single capture (`Id`) and `{..name}` splices a repeated capture
-(`Vec<Id>`).
+### Raw captures (`@@name`)
+
+The default `@name` capture marker is *auto-translated*: in OneShot
+phases the macro recursively translates the captured node before
+binding it, so `{name}` in the output template splices a node that
+already conforms to the output schema.
+
+For rules that need the raw (input-schema) capture — typically to read
+its source text or to translate it explicitly with mutable context
+state between calls — use `@@name` instead. The body sees the original
+input-schema `Id`:
+
+```rust
+yeast::rule!(
+    (assignment left: (_) @@raw_lhs right: (_) @rhs)
+    =>
+    {
+        // raw_lhs is untranslated: read its original source text.
+        let text = ctx.ast.source_text(raw_lhs);
+        // rhs is already translated by the auto-translate prefix.
+        tree!((call
+            method: (identifier #{text.as_str()})
+            receiver: {rhs}))
+    }
+);
+```
+
+Mix `@` and `@@` freely in the same rule. In a Repeating phase both
+markers are equivalent (auto-translation is a no-op for repeating
+rules).
