Restructuring and Maintenance

[Tjemmmic]

Description

This PR addresses the restructuring and maintenance that aims to simplify the repository structure and move it into being used in Gadget Blueprints.

List of Changes

Structure Changes

• Moved eigensdk-rs from a subdirectory to the root of the project - this removes the self-titled crate that re-exports the crates.
• Moved dependency imports to Workspace level
• Completely removed Gadget crates so that Gadget can import EigenSDK-RS
• Removed Executor from use in the Tangle AVS - Tangle Validator is run directly using Commands
• Removed Tangle AVS - it is basically being replaced by the Tangle AVS blueprint in Gadget

Bug Fixes

• Fixed a version mismatch issue plaguing Foundry imports
• Updated everything based on Alloy changes that broke Foundry and Anvil
