Implement Falcon-based authentication and Implement SOLO Localhost mining

[NamecoinGithub]

This is a PR request targeting Testnet, so it can possibly be integrated with Upstream Codebase bringing New Upgraded Features in the Future, alongside the reliable and good designed Base Architecture.

I built a Nexus Interface .deb for Linux with the Stateless Mining Server NODE built in.

The testing should allow the GUI to Stake and Mine at the same time. However the Command Line LLL-TAO is a better/required option for real Pool Nodes, but the GUI is good for someone who can Stake and Mine at the same time using CPU. GPU testing and support for Miner will come later!

CPU Mining is Solid without any errors for weeks of Mining. Although it's just CPU mining available in the build, it's the PROCESS that is in a near term Refined finished state.

UPGRADED FALCON 512 TO == FALCON 1024 default keys for Signing are still Falcon512, but default keys for MINER-NODE handshake is Falcon1024. Whatever the MINER keys in will also be the same size for it's Block Found Submit Disposable Falcon Size either Falcon512 or Falcon1024.

Legacy Server 8 Bit OPCODES and Stateless Server is 16 Bit Opcodes

CREATE NEW TRITIUM POW STATELESS MINING SERVER with FALCON AUTH ++++++++ FALCON 1024 Bit DEFAULT for DISPOSABLE FALCON

MINIMAL NON-TESTED Remote Node POOL DISCOVERY BUILT IN

MINIMAL SOLO MINING WORKING/POLISHED BUT COLIN CANTRELL WILL INSERT/DELETE TO FIT THE PURPOSE, 95% OF THE TOTAL WORK/CODING IS FINISHED/ Nexusoft/LLL-TAO#1 I STAYED IN MY LANE OF DEALING WITH ONLY MINING INFRASTRUCTURE CODE WITHIN NODE. AND CREATED MY OWN STATELESS MINING UTILITY WORKSHOP, AND MANY CONSTANTS UTILITIES ALONG WITH AAD, OPENSSL EVP DOMAINS, MANY AWESOME OTHER UPGRADES.

FULL DOCUMENTATION SECTIONS, STILL NEEDS FINAL POLISH, WORK. MOST OF THE CODE IS FROM A WHOLE HOST OF TRIAL AND ERROR TO LEARN ABOUT NEXUS CODEBASE. BUT I LEARNED THE HARD WAY, SO NO ONE ELSE HAS TO FIGURE IT OUT THEMSELVES. FOR THIS I CREATED A HUGE REPOSITORY OF DOCUMENTS WITH CROSS-REFERENCED LINKS, FOR BOTH CONFIG OPTIONS AND NEXUSMINER TIE-INS FOR CODE KEYWORDS.

NexusMiner TOML config is a incredible upgrade over JSON Miner Parsing.

The Release Miner has the cpu.config file included.

Command Line Linux is Capitalization sensitive.

Open Terminal where the Miner is located AFTER the Nexus NODE is started with Autologin.

start the miner=

This pull request introduces a comprehensive developer experience overhaul for the Nexus LLL-TAO project, focusing on modernizing the build, development, and CI/CD infrastructure. The main changes include adding DevContainer support, improved build and test documentation, streamlined CI workflows for both Linux and Windows, and explicit dependency management. These updates make it much easier for developers (and GitHub Copilot agents) to set up, build, test, and contribute to the project in a reproducible way.

Key changes by theme:

DevContainer and Local Development Environment:

• Added a complete .devcontainer/devcontainer.json for VSCode DevContainer support, specifying Ubuntu 22.04, required features, port forwarding, and recommended VSCode extensions/settings. This enables one-command reproducible development environments.
• Introduced .devcontainer/setup.sh to automate dependency installation, environment validation (including Berkeley DB check), workspace permissions, and provide clear post-setup instructions.

Build and Dependency Documentation:

• Added .github/copilot-instructions.md with detailed build, dependency, and testing instructions, including troubleshooting and code modification guidelines for both Linux and macOS.
• Added .github/copilot-instructions.yml to explicitly declare build/test requirements and dependencies for Copilot agents and CI.

Continuous Integration and Validation Workflows:

• Added .github/workflows/devcontainer-validate.yml to automatically build, test, and validate the project in a CI environment, ensuring that the codebase is always buildable and testable from a clean state.
• Added .github/workflows/copilot-setup-steps.yml for dependency installation validation, supporting both manual and PR-triggered runs.
• Added .github/workflows/release-windows-node.yml to build, package, and upload a portable Windows node binary using MSYS2/MinGW, facilitating cross-platform releases.

Project Metadata and Templates:

• Added a LICENSE file (MIT License) for clear open-source licensing.
• Added .github/PULL_REQUEST_TEMPLATE_AGENT.md to standardize PR descriptions for coding agents, improving reviewability and clarity.

Cleanup:

• Removed the old Dockerfile for the previous Debian-based build, as the new DevContainer setup supersedes it.

These changes collectively modernize the developer workflow, improve onboarding, and ensure robust, repeatable builds and tests across platforms.

Working Releases for Localhost CPU mining without any bugs 2 full weeks of Continuous Mining, only STALE blocks are rejected.

Merging isn't required for me to keep developing, but Months of Review is expected!

Thanks!
