feat: add developer workflow shortcuts to Makefile

[2PykeETH]

Summary

This PR introduces a set of developer workflow shortcuts in the Makefile to simplify common tasks and improve development speed.

---

Changes

makefile

• Added Developer Workflow Shortcuts section with new commands:
  • dev → installs dependencies, builds, and runs tests (quick setup)
  • quick-test → runs a fast unit test cycle
  • deploy-test → deploys contracts to Sepolia and runs testnet interaction
  • full-check → executes complete code quality checks (formatting, build, coverage, gas snapshot, analysis)

---

Benefits

• Speeds up common developer workflows with one-line commands
• Standardizes development practices across contributors
• Reduces cognitive load by grouping frequently used steps

---

Next Steps

• Add CI integration for full-check to enforce quality standards
• Extend shortcuts with linting, docs generation, or security scans
