Enforce Quality Gates for Java (Error Prone/NullAway) and Python (Pylint/Pyright)

[ndegwamartin]

Objective

Configure our CI pipeline to act as a "Quality Gate" by running static analysis and type checking for all sub-projects. The build must fail if any tool detects a violation.

Technical Context

We need to ensure that the following tools are not just "reporting," but are actively blocking merges:

Python Sub-projects

• Pyright: Enforce static type checking to catch type mismatches.
• Pylint: Enforce coding standards and error detection.
• Black: Run in --check mode. The build must fail if the code is not formatted according to our standard.

Java Sub-projects

• Error Prone: Hook into the compiler to catch common programming mistakes at compile time.
• NullAway: Enforce nullability checks (via Error Prone) to eliminate NullPointerExceptions.

Pre-requisite

This tickets depends on merging these PRs

• Enable Static Type Checking for Python Sub Projects with Pyright #1520
• Refactors ErrorProne and NullAway configuration to root pom #1540
