fix: replace hardcoded macOS path with dynamic PROJECT_ROOT variable in DXT build script

The build-dxt-clean.sh script had /Users/arul/Projects/ncp-production-clean hardcoded in multiple places, causing permission errors on Linux CI runners. Now uses PROJECT_ROOT=$(cd $(dirname ${BASH_SOURCE[0]})/..; pwd) to dynamically determine the project root directory, making it portable across all environments.
