Use system2() with separate args instead of shell-interpolated system()
calls in .send_desktop_notify() and .send_webhook(). This eliminates
command injection risk when msg, status, url, or payload contain shell
metacharacters.
- #5: Unwrap _brand.yml for Quarto 1.9+ compatibility (remove top-level
brand: wrapper so meta/logo/color/typography are at the top level)
- #1: Add quiet parameter to na_sum() to suppress warnings in loops/pipelines
- #3: Add beep() function for CLI beep, desktop notifications, and webhook
alerts (supports type=beep|notify|webhook|all)
