+add verbose build output, progress logging, and timing for builds/tests
+
+- Add 'verbose' option to build/test flows (interfaces, CLI, and method signatures) to allow streaming raw docker build output or run silently
+- Log per-item progress for build and test phases (e.g. (1/N) Building/Testing <tag>) and report individual durations
+- Return elapsed time from Dockerfile.build() and Dockerfile.test() and aggregate total build/test times in manager
+- Introduce formatDuration(ms) helper in logging module to format timings
+- Switch from console.log to structured logger calls across cache, manager, dockerfile and push paths
+- Use silent exec variants when verbose is false and stream exec when verbose is true
+
 ## 2026-02-06 - 1.8.0 - feat(build)
 add optional content-hash based build cache to skip rebuilding unchanged Dockerfiles
