Introduces a reusable GitHub Action for building documentation and updates all platform build workflows to install documentation dependencies and run 'make docs'. This ensures documentation is built and available as part of the CI process across Linux, macOS, and Windows. Also updates the docs workflow to adjust pip dependencies.
Appends 'alpha' to artifact tag suffix for pull requests in the GitHub Action and changes the build folder name from 'build/Release' to 'build/release' in the Makefile for consistency.
Refactors Makefile and Dockerfile to support static builds via a STATIC variable, simplifying static build targets. Updates genesis transaction data and public key in generated files. Improves GitHub Actions artifact upload by refining tag and prerelease logic.
