[Feature] Add a --quiet flag for compact node installation output

[Kinasa0096]

Problem

Node installation can produce hundreds of lines of per-package progress output from the underlying cm-cli / pip subprocesses. This becomes difficult to review when installing many node packs, especially when terminal progress bars are captured as separate log lines.

This was previously discussed in #442. The maintainer suggested opening a focused request for a --quiet-style flag.

Proposed behavior

Add a --quiet flag to the applicable node installation commands.

When --quiet is enabled:

• Suppress routine subprocess progress bars and per-package download progress.
• Keep warnings and errors visible.
• Show a concise final success/failure result for each requested node pack.
• Preserve the normal exit code so scripts can reliably detect failures.

Without --quiet, keep the current output unchanged for backward compatibility.

Expected result

Installing many node packs with --quiet should produce a short, reviewable log containing the requested node packs, important warnings/errors, and final results, without a separate line for every progress-bar update.
