[dylanlott]

TL;DR

Bump version from 0.6.0 to 0.7.0 across all workspace packages.

What changed?

• Updated the workspace package version from 0.6.0 to 0.7.0 in the root Cargo.toml
• Updated all internal dependency versions from 0.6.0 to 0.7.0 for all signet crates:
  • signet-bundle
  • signet-constants
  • signet-evm
  • signet-extract
  • signet-node
  • signet-rpc
  • signet-sim
  • signet-types
  • signet-tx-cache
  • signet-zenith

How to test?

• Verify that the project builds successfully with cargo build
• Run tests to ensure all dependencies resolve correctly with cargo test
• Check that any downstream projects depending on these crates can update to the new version

Why make this change?

This version bump prepares for a new release with significant changes that warrant a minor version increment according to semantic versioning principles.
