Shortly after the release of Bun 1.3.0, I tried to build this thing without vendored dependencies yet again. Unfortunately, this wasn't successful at all. I do not like the result as it goes against the Homebrew approach but at least it works (and I guess this is when we can make an exception)

Disabling new formula checks as it requires newer ruby and libiconv. For some reason the audit complains about the resource URL (even after adding it to binary_bootstrap_formula_urls_allowlist.json)

Pull Request Overview

This PR introduces a new Homebrew formula for Bun 1.3.0, a JavaScript runtime, bundler, test runner, and package manager. The formula uses vendored dependencies and requires a bootstrap binary to build, which is a deviation from typical Homebrew practices but necessary due to build complexity.

Key Changes:

• New formula for Bun 1.3.0 with comprehensive build dependencies
• Bootstrap binary resources for multiple platforms (macOS/Linux, ARM/Intel)
• Allowlist entry for binary bootstrap URLs to pass style checks
