Deno 2.8

Deno 2.8 introduces four major new subcommands: `deno audit fix` automatically upgrades vulnerable npm packages, `deno bump-version` updates version numbers in configuration files with workspace support, `deno ci` provides a dedicated command for reproducible installations in CI environments, and `deno pack` builds Deno projects into npm-publishable tarballs. These additions represent Deno's largest minor release to date, streamlining dependency management, versioning, and npm publishing workflows.
