fix(release): add proper release workflow with version injection

- Make AppVersion injectable via ldflags at build time
- Replace GoReleaser with simple GitHub Actions workflow
- Build for linux/darwin/windows on amd64/arm64
- Generate checksums.txt for integrity verification
- Inject version from git tag into binary

Fixes #37
