Speed up build process for CD

[portuu3]

Issue tracking

closes #3547

Context behind the change

Added a script that:

• Detects current branch and compares against origin/main to see if core, sdk, or logger changed.
• For the target workspace, replaces any workspace:* deps with the latest published npm versions, unless the corresponding package changed locally.
• If core/sdk/logger changed, it builds them.
• Finally focuses the requested workspace so only its dependencies are installed.
• NPM use can be forced setting USE_NPM_PACKAGES=true

How has this been tested?

Tested locally and on Render

Pull request overview

This PR speeds up the CD build process by introducing a selective build strategy that only builds and installs dependencies for packages that have changed compared to the main branch.

Changes:

• Added a new build script that detects changed packages (core, sdk, logger) and conditionally builds them
• Modified job-launcher server dependencies to include core and ethers packages
• Disabled Yarn's transparent workspaces feature to support the new build approach
