Fix broken build and add useful scripts

[yvonnezhangc]

Summary

This PR unblocks CI, modernises the tool-chain, and adds first-class developer utilities for package deployment and transaction debugging.

Detail

Build & CI

• scripts/shell/setup.sh
  • Upgrades Aptos CLI to v7.5.0 and installs binaries in $HOME/.aptos/bin (works on CI Ubuntu and local macOS).
  • Fails fast (set -e) and exposes $APTOS_BIN for downstream scripts.

Move tool-chain

• Makefile – bumps compiler_version and language_version from 1 → 2.
• AptosFramework dependency is now pinned to commit 1381c93f… for deterministic builds.

Packages & Deps

• @aptos-labs/ts-sdk upgraded to 1.33.0; adds "packageManager" field for parity with Renovate.

New TypeScript CLI commands

• decode-transaction – BCS → human JSON (supports argument decoding for upgradePackage).
• deploy – one-shot package builder / publisher with optional source verification.
• execute-transaction – offline-sign, dry-run or submit (supports multi-sig).
  • Supporting utils: address normalisation fixes, deploy helpers, etc.

Testing

• New mocha test suites cover:
  • Transaction decode logic (incl. fee-payer and no-decoder paths).
  • End-to-end deploy flow (with / without source verification).
  • Single-sig and multi-sig transaction execution (dry-run & submit).
• CI passes on Node 20.14 / Yarn 1.x.
• Manual smoke-test: make start-network && yarn scripts deploy ….
