Add signed source releases via sigstore - #258
Merged

Conversation
Create an immutable source tarball at each release tag, sign it with sigstore, and attach the tarball, .sigstore.json bundle, and a .sha256 checksum to the GitHub release — following the pattern OpenEXR and other ASWF projects use. Also runnable via workflow_dispatch to sign an existing release retroactively. Uses the same pinned sigstore action the binary-signing steps in build.yml already use. Fixes #249.
