build(deps): override follow-redirects to 1.16.1 for high-severity advisories

Clears GHSA-q3jh-wrc6-jgq8 and GHSA-8r9p-f939-6h3c (via axios), which fail the bun audit step in CI.

On macOS it then checks `/opt/homebrew/bin/mpv`, `/usr/local/bin/mpv`, and `/Applications/mpv.app`, because an app opened from Finder, the Dock, or Spotlight does not get your shell's `PATH`.
