Description

**Is your feature request related to a problem? Please describe.**
GnuPG is a large amount of legacy C code that operates on untrusted input.

**Describe the solution you'd like**
Use Sequoia instead. Only signature verification is needed.

**Describe alternatives you've considered**
Use a different tool for verifying signatures, such as signify or ssh-keygen.

**Additional context**
GnuPG has known bugs and will decompress data in the signature, creating extra attack surface.

Research direction

Start by locating the current GnuPG signature-verification integration and documenting its entry points and verification flow. Assess how Sequoia can provide signature verification only, then define completion as replacing the GnuPG path while preserving required verification behavior and avoiding its decompression of signed data.
