Extend `FindRelatedPrimitives` tool queries for all languages

[data-douser]

Develop comprehensive FindRelatedPrimitives.ql tool queries for each supported language to discover CodeQL classes, predicates, and types relevant to a source code location.

Query Output Schema

| primitiveType | primitiveName | definitionFile | definitionLine | relevanceScore |

Implementation Design

1. Query Structure (server/ql/{lang}/tools/src/FindRelatedPrimitives/)

   • FindRelatedPrimitives.ql: Main entry point query
   • Parameterized by: file, startLine, endLine, startColumn, endColumn

2. Primitive Discovery Logic

   • AST Types: Find CodeQL classes that match AST nodes at location
   • Type Predicates: Discover getType(), getAQualifiedName() accessors
   • Dataflow Nodes: Map to DataFlow::Node subtypes when applicable
   • Taint Sources/Sinks: Identify if location matches known sources/sinks
   • Control Flow: Find relevant ControlFlowNode and BasicBlock types

3. Relevance Scoring

   • Direct AST match: score 100
   • Parent/child AST types: score 75
   • Related dataflow concepts: score 50
   • Tangentially related types: score 25

4. Per-Language Implementation
   Required for: actions, cpp, csharp, go, java, javascript, python, ruby, swift

Acceptance Criteria

• Query implemented for all 9 languages in server/ql/{lang}/tools/
• Unit tests with .expected files for each language
• Results ranked by relevance score
• Integration with codeql_query_run tool for execution
