Implement production and development build targets with binary size optimization

Browse Source 
- 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
