feat: pin casbin version and drop Node.js 18 to fix CI test failures

[Copilot]

fix: #33

CI fails with Cannot find module 'csv-parse/sync' when running tests. The workflow uses yarn install --no-lockfile, which installs the latest compatible versions of dependencies. With casbin specified as ^5.2.1, yarn can install v5.10.0 or later, which requires csv-parse as a dependency. Additionally, Node.js 18 was incompatible with the which@6.0.0 transitive dependency that requires Node >= 20.17.0.

Changes

• Pin casbin to exact version 5.2.1 (remove caret ^) in devDependencies
• Update CI workflow to only run tests on Node.js 20 (drop Node.js 18 from the matrix)

This prevents yarn from automatically upgrading to newer casbin versions that require csv-parse. Version 5.2.1 doesn't require csv-parse, eliminating the dependency issue. Dropping Node.js 18 from CI avoids compatibility issues with newer transitive dependencies. This approach addresses the root cause of version drift when using --no-lockfile rather than adding workarounds.

Fixed in 6bb0bfd. The issue was using csv-parse v5 instead of v4. casbin v5.10.0 requires csv-parse ^4.15.3, updated the dependency to match.

Fixed in 7f725ea. The issue was that ^5.2.1 allowed yarn to install casbin v5.10.0+ (which requires csv-parse). Pinned casbin to exact version 5.2.1 which doesn't require csv-parse, preventing version drift when using --no-lockfile.

Done in 7bda693. Updated CI workflow to only run on Node.js 20, removed Node.js 18 from the matrix.
