HardKAS: Execution-safe development for Kaspa

HardKAS is a deterministic, local-first developer operating system and framework for building Kaspa applications.

It provides developers with a reproducible CLI, local execution runtime, artifact engine, and simulation tools to replace the traditional "request-and-hope" blockchain development cycle with strict cryptographic accountability.

Key Principles

• Local-first execution: Build and test against a deterministic simulator instantly, or boot a real dockerized Kaspa simnet when you need true node validation.
• Evidence-driven: Every transaction intent, signature, and receipt is materialized as an artifact on disk, forming an unbroken Evidence DAG.
• Developer Infrastructure, not Custody: HardKAS orchestrates safety during development (e.g., maturity filtering, pending-spend protection) but relies on Kaspa consensus for finality.
