Feature/add slsa and mvr info

[avernikoz]

This PR introduces SLSA (Supply-chain Levels for Software Artifacts) compliance and MVR (Move Verification Registry) provenance for verified package publishing. It also updates the Sui compiler version and refines CI workflows.

Key Changes

• SLSA & MVR Provenance:
  • Added a new GitHub workflow .github/workflows/publish_package.yml that utilizes the sui-mvr-provenance action for secure, verified deployments with SLSA Level 3 compliance.
  • Introduced packages/deeptrade-core/mvr.config.json to configure registry metadata (name, description, contact info, etc.) for the MVR.
• Sui Version Upgrade:
  • Bumped the Sui version from 1.56.2 to 1.62.1 across CI configurations (move_test.yml) and the project lockfile.
• CI/CD Enhancements:
  • Optimized triggers in .github/workflows/move_test.yml to specifically target relevant Move and workflow file changes.
• Contract Configuration:
  • Reset the deeptrade_core address to 0x0 in Move.toml, following deployment best practices for upgrades and new builds.
• Dependency & Environment Updates:
  • Updated Move.lock with the new compiler version and latest framework revisions.
  • Removed legacy environment-specific deployment IDs from Move.lock to ensure a clean build state.
• Documentation: Removed the redundant packages/deeptrade-core/README.md to consolidate documentation within the repository root.
