Fix: Ensure cross-platform compatibility for sed command in CI script

[voronor]

Problem

In the CI script, the following command can cause issues on macOS:

sed -i '/,0/d' lcov.info

The sed -i flag directly edits a file in place, but its behavior differs across platforms:

• On Linux, it works as expected.
• On macOS, the -i option requires an argument for the extension of a backup file (even if it’s empty). Without this, the script fails.

Proposed Fix

To ensure compatibility across both Linux and macOS, we updated the script to detect the operating system and adjust the sed command accordingly.

Changes Made

1. Added logic to check the operating system using $OSTYPE.
2. Modified the sed command to use sed -i '' on macOS and sed -i on Linux.

Updated Code

if [ "${CI:-"false"}" == "true" ]; then
  # Foundry coverage
  forge coverage --report lcov --ir-minimum
  # Remove zero hits
  if [[ "$OSTYPE" == "darwin"* ]]; then
    sed -i '' '/,0/d' lcov.info
  else
    sed -i '/,0/d' lcov.info
  fi
fi

Importance of Fix

1. Cross-platform Compatibility: Ensures the script runs successfully on both Linux and macOS environments.
2. Robust CI/CD Process: Prevents test pipeline failures caused by platform-specific inconsistencies.
3. Improved Developer Experience: Developers using macOS will no longer encounter errors when running the script locally or in macOS-based CI workflows.
