chore(eslint): remove package-level unused-vars overrides

[Sheraff]

Summary

• Remove package-level unused-imports/no-unused-vars disables from router/start package ESLint configs.
• Keep the root ESLint behavior unchanged so packages inherit the shared unused-vars policy.
• Let CI surface any package-specific follow-up needed instead of maintaining broad local opt-outs.

Summary by CodeRabbit

• Chores
  • Updated code quality enforcement configurations across multiple packages to ensure consistent development standards.
