Issue:
Our CI/CD pipeline currently triggers builds and deployments for every code change, including when there are no changes in core application files (e.g., .rs, cargo.toml, cargo.lock, fly.toml, DockerFile) or when only test files are modified.

Expected Behavior:
The pipeline should:

1. Identify and act based on the nature of code changes.
2. Trigger builds and deployments only when changes can potentially alter the binary/artifact.
