📝 Walkthrough

Walkthrough

The pull request modifies the CI/CD workflow to introduce a matrix strategy for testing with interpreted and bytecode modes, conditionally passing mode flags to the test runner, and enabling error continuation for WebAssembly tests.

Changes

Cohort / File(s)	Summary
CI/CD Workflow Configuration .github/workflows/pr.yml	Added matrix strategy with mode parameter [interpreted, bytecode] and fail-fast set to false. Updated test command to conditionally pass --mode=bytecode flag based on matrix selection. Enabled continue-on-error for wasm-test job.

Poem

🐰 Hopping through workflows with bytecode delight,
Two paths to run tests, both handled just right,
Interpreted, compiled, no failures we fear,
The tests march on forward with wisdom so clear! ✨
