Add Workflow Concurrency to Save CI Resources

[Shubh-Raj]

Feature Request

Add concurrency configuration to the GitHub Actions workflows to cancel redundant builds.

Use Case

When a developer pushes multiple commits to a PR in quick succession, multiple GitHub Action workflows are triggered and run in parallel. This wastes CI resources and can delay feedback for the latest commit.
We should automatically cancel any in-progress runs for the same branch/workflow when a new commit is pushed.

Possible Solution

Add the concurrency group implementation to the build.yml workflow:

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: true

Context

Optimizing CI usage to be faster and more cost-effective.

Detailed Description

Update .github/workflows/build.yml to include the concurrency block.
