refactor: use NESTING_TYPES.has() in getComplexityIncrement for Java and Python

[github-actions]

🤖 This is an automated pull request from Repo Assist.

Summary

Removes duplicated node-type listings in getComplexityIncrement() for the Java and Python analyzers, using the existing NESTING_TYPES static Set as the single source of truth.

Motivation

Both javaAnalyzer.ts and pythonAnalyzer.ts maintained the same list of node types in two places:

1. NESTING_TYPES — a ReadonlySet<string> that controls nesting-level bumps for child traversal.
2. getComplexityIncrement() — a switch statement that returns 1 + this.nesting for exactly those same node types.

Adding a new construct (e.g. a new loop type) required updating both locations. Missing one would silently produce wrong nesting increments.

Change

Replace the redundant switch cases with a single NESTING_TYPES.has() guard at the top of getComplexityIncrement(). The Set is an O(1) lookup — no performance impact.

Java (javaAnalyzer.ts): eliminates 9 case statements (8 nesting-group cases + the identical separate lambda_expression case)

Python (pythonAnalyzer.ts): eliminates 9 case statements (the 9 NESTING_TYPES cases)

Only flat increments (ternary_expression, elif_clause, else_clause, conditional_expression) and special-case increments (binary_expression, boolean_operator) remain in the switch.

No behavior change

The NESTING_TYPES sets are unchanged; getComplexityIncrement returns identical values for all inputs.

Pull request overview

This PR refactors the Java and Python cognitive complexity analyzers to remove duplicated “structural increment” node-type lists by using each analyzer’s existing NESTING_TYPES Set as the single source of truth in getComplexityIncrement().

Changes:

• Java: Replace the structural switch cases in getComplexityIncrement() with an early NESTING_TYPES.has(node.type) guard.
• Python: Replace the structural switch cases in getComplexityIncrement() with an early NESTING_TYPES.has(node.type) guard.
• Update the related doc comments to clarify that structural increments are driven by NESTING_TYPES.
