# This workflow will build a golang project for Gitea Actions
# Using inline commands to avoid external action dependencies
#
# NOTE: All builds use CGO_ENABLED=0 since p8k library uses purego (not CGO)
#       The library dynamically loads libsecp256k1 at runtime via purego
#
# Release Process:
# 1. Update the version in the pkg/version/version file (e.g. v1.2.3)
# 2. Create and push a tag matching the version:
#    git tag v1.2.3
#    git push origin v1.2.3
# 3. The workflow will automatically:
#    - Build binaries for Linux AMD64
#    - Run tests
#    - Create a Gitea release with the binaries
#    - Generate checksums
