Add a quiet mode that suppresses all build progress output (target names, status messages, info) while still printing errors. Useful for scripting or CI where only failures matter. The flag is propagated to child processes via the REDO_QUIET environment variable, so the entire build tree stays silent.
10 tests covering: - Silent output on successful build - Normal mode still shows output (control test) - Errors still printed in quiet mode - Quiet propagates to nested child builds - --quiet long form - -q combined with -k flag - Multiple targets with -q - Build correctness unaffected by -q - Nested build errors show error chain in quiet mode - Warnings are not suppressed by -q

Summary
Add a quiet mode (
-q/--quiet) that suppresses all build progress output while still printing errors. On a successful build, redo produces no output at all.Motivation
When running redo in scripts, CI pipelines, or as part of larger build systems, the per-target progress output could be considered noise. A quiet flag lets users opt into silence and only see failures (and warnings).
