fix(cli): clean build output by hiding internal steps and cache logs

- hide artifact cache line from default output (verbose only)
- filter internal ninja step: 'Copy compile_commands.json to project root'
- improve build UX by showing only meaningful compilation/link steps
- keep output clean, product-focused, and user-friendly
