build: add test-ci target and use it in CI

[cboone]

Summary

• make build now runs unit tests before compiling by splitting compile-only work into a new binary target
• added a dedicated test-ci target that runs the deterministic CI suite via test-all
• updated the CI workflow to call make test-ci so test orchestration is defined in one place

Testing

• make test-ci

Pull request overview

This PR reorganizes the build and test workflow to better centralize test orchestration in the Makefile. The build target now runs unit tests before compiling (with a new binary target for compile-only work), and a dedicated test-ci target consolidates the CI test suite definition in one place instead of having it split between the Makefile and CI workflow.

Changes:

• Refactored build target to run unit tests before compilation, with binary target for compile-only operations
• Added test-ci target that orchestrates the complete CI test suite via test-all
• Updated CI workflow to delegate all test orchestration to make test-ci
