fix(aqua): improve GitHub token handling for sigstore verification

[jdx]

Summary

• Improves GitHub token handling for sigstore verification in the aqua backend
• Uses env::GITHUB_TOKEN instead of manual environment variable checking
• Adds build dependencies to the dev Dockerfile for better development experience

Changes Made

• GitHub Token Handling: Replaced manual env::var("GITHUB_TOKEN").ok().or_else(|| env::var("GH_TOKEN").ok()) with env::GITHUB_TOKEN.as_ref().cloned() for cleaner and more consistent token access
• Dev Dockerfile: Added clang, libclang-dev, and pkg-config build dependencies to support compilation requirements
• DevContainer: Added MISE_TRUSTED_CONFIG_PATHS environment variable and auto-install on container creation

Testing

• GitHub token handling follows mise's established environment variable patterns
• Build dependencies ensure proper compilation in development containers
• All changes maintain backward compatibility

Pull Request Overview

This PR improves GitHub token handling for sigstore verification in the aqua backend and enhances the development environment setup. The changes simplify token access by leveraging mise's environment variable patterns and add necessary build dependencies for development containers.

• Replaces manual GitHub token environment variable checking with mise's standardized env::GITHUB_TOKEN approach
• Adds essential build dependencies (clang, libclang-dev, pkg-config) to the development Dockerfile
• Configures DevContainer with trusted config paths and auto-installation

Bug: GitHub Token Retrieval Loses GH_TOKEN Compatibility

The GitHub token retrieval logic no longer explicitly falls back to the GH_TOKEN environment variable. This removes compatibility for users and CI systems that rely on GH_TOKEN as an alternative to GITHUB_TOKEN.
