Add ESLint to ani-cursor and include in CI

[captbaritone]

Summary

The ani-cursor package had no lint script and wasn't being linted in CI.

Changes

• Added lint script to ani-cursor/package.json: eslint src --ext ts,js
• Added ani-cursor#lint task to turbo.json so it runs alongside other packages during CI

Testing

• Verified locally that pnpm run lint passes with no errors
• Confirmed the lint rules work by intentionally introducing a formatting error and seeing it caught by prettier/prettier rule
