Manjikaze's auto-update mechanism pulls and executes code from the repository without verifying who authored it. If someone gains push access (e.g. through a compromised GitHub account), they could inject malicious code that runs automatically on every developer's machine.
This PR implements a GPG Certificate Authority (CA) trust model. Instead of maintaining a list of individual trusted GPG fingerprints, we use a single trust anchor: the 10KB Code Signing CA to verify the entire chain.
A commit is only accepted if it is signed by a GPG key that has been certified by the CA. Keys not signed by the CA are rejected, regardless of whether they exist on a keyserver.
