✨ Summary

This PR adds proper support for the --quiet flag in both the pinoc build and pinoc test commands.

When the --quiet flag is used:

• For build: it passes the --quiet argument after -- to cargo build-sbf
• For test: it suppresses both stdout and stderr using Stdio::null(), ensuring no noisy test output is shown

This improves UX in CI environments or when developers want cleaner command output.

Changes

• pinoc build:
  • Updated to pass -- --quiet to cargo build-sbf when --quiet is specified
• pinoc test:
  • Updated to pass --quiet to cargo test correctly
  • Redirects output streams to /dev/null via Stdio::null() when --quiet is used

Example usage

pinoc build          # shows build output
pinoc build --quiet  # suppresses build output

pinoc test           # shows test results and logs
pinoc test --quiet   # suppresses test logs and output
