feat: Web3.py v6 to v7 Migration (Boring AI Hackathon)

[Rohan5commit]

Boring AI Hackathon Submission: L-Tier

Submitting an L-Tier codemod for the Web3.py v6 to v7 migration.

This migration requires deep architectural changes (migrating from functional middleware to class-based Web3Middleware) that breaks hundreds of projects.

Features:

• Deterministic handling of 15+ breaking API changes (WebsocketProviderV2, .ws -> .socket, Exceptions, AttributeDict) to ensure Zero False Positives.
• Generative AI (NVIDIA NIM Llama 3 70B) securely sandboxed only to translating functional middleware AST nodes.
• Explicit warnings for deprecated modules without blindly deleting code to preserve build safety.

This matches the ~2 week effort (L-Tier) complexity scope.

Thank you for participating in the hackathon. Please create a dedicated public repo in your personal GitHub account and put the codemod over there. (Feel free to draw inspiration from this repo on folder structure and best practices and GitHub actions for automating the publishing experience with changeset)
Thank you.
