- Add LDFLAGS_BASE for version info only, LDFLAGS for production (with -s -w optimization), and LDFLAGS_DEV for development - Create 'build' target (production) that strips symbols, reducing binary size by ~30% (56MB -> 39MB) - Create 'build-dev' target (development) that keeps debug symbols for profiling - Update 'docker-build' to pass BUILD_FLAGS="-s -w" for optimized production images - Create 'docker-build-dev' target that builds development images with notifier:latest-dev tag and no optimization - Update Dockerfile to accept and use BUILD_FLAGS argument in build stage - All targets now clearly indicate their optimization level in output messages
