edgefirst-imu 3.0.0

# GitHub Actions workflow for publishing releases
#
# This workflow orchestrates release publishing when a version tag is pushed:
# - Creates GitHub Release with binaries and SBOM
# - Publishes to crates.io using trusted publisher
#
# Release Process:
# 1. Update version in Cargo.toml
# 2. Update CHANGELOG.md with version entry
# 3. Commit and push changes
# 4. Create and push tag: git tag v3.0.0 && git push --tags
#
# crates.io Trusted Publisher Setup:
# 1. Go to https://crates.io/crates/edgefirst-imu/settings
# 2. Add trusted publisher: EdgeFirstAI/imu, release.yml, publish-crates
#
# Action Versions (verified January 2026):
# - actions/checkout@v4
# - actions/download-artifact@v4
# - softprops/action-gh-release@v2
# - dtolnay/rust-toolchain@stable
