I went through this recently with Haven and had the same objection about “Trusting GitHub and random GitHub Actions with my private key.”
What I did was:
1. Created a new independent key for Haven (with UID haven@bitvora.com instead of my own). The master key only has cert capabilities.
2. Created a new signing subkey.
3. Gave GitHub only a copy of the signing subkey (without the master / cert key). Both the private key and passphrase are stored as secrets. I’ve since rotated the passphrase on the key uploaded to GitHub.
4. I use GoReleaser and GitHub Actions to GPG-sign releases.
5. Both nostr:nprofile1qqsw9n8heusyq0el9f99tveg7r0rhcu9tznatuekxt764m78ymqu36cpr3mhxue69uhhyetvv9ujucnfw33k76twwpshy6ewvdhk6tcpzdmhxue69uhhwmm59e6hg7r09ehkuef0qy2hwumn8ghj7un9d3shjtn4w3ux7tn0dejj7ne6u4e and I have copies of Haven’s master key and revocation certificates. If the subkey is ever compromised, we can easily revoke it and create a new signing subkey.
6. Users can find Haven’s public key in the GitHub repository and on keys.openpgp.org.
Commits, tags, etc. are still signed with my own key. GoReleaser checksums binary artifacts and signs those checksums with Haven’s key.
I haven't taken the time to make the builds fully (as in, bit by bit) reproduceable, but this can be done by modifying the pipeline t use commit information as part of the build ( https://goreleaser.com/blog/reproducible-builds/ ).
Another option is to bypass PGP altogether and sign releases with something like cosign. But hey, if it works for Fedora, Debian, Arch, etc., it works for me too.

should be doing it now, thanks for the tip!
