Release Viyal · bytebunkers/viyal

This is a massive update introducing a brand-new compiler architecture, an advanced optimization pipeline, and automated cross-platform distribution.

🚀 New Features & Architecture

File Extension Change: The official language file extension has been renamed from .vy to .vyl across the entire ecosystem.
New Middle Intermediate Representation (MIR): Introduced a brand new MIR layer (compiler/mir) and mir_compiler.rs to bridge the gap between High-Level IR (HIR) and Bytecode.
Advanced Optimization Pipeline: Added a comprehensive, multi-pass optimizer (compiler/optimizer) which brings massive performance improvements before bytecode generation. The new passes include:
- Static Single Assignment (SSA) and De-SSA construction.
- Control Flow Graph (CFG) generation.
- Constant Folding.
- Dead Code Elimination (DCE).
- Global Value Numbering (GVN).
- Sparse Conditional Constant Propagation (SCCP).
Compiler Backend Layer: Scaffolded a new backend abstraction (compiler/backend) for future native/JIT compilation targets.

Runtime & VM Enhancements: Major updates and stability improvements to the Garbage Collector (runtime/gc), Async runtime, Concurrency model, and the core Virtual Machine object model.
Toolchain Upgrades: Refactored and improved all core language tooling including the CLI, Static Analyzer, Formatter, Debugger, and the Language Server Protocol (LSP).
Compiler Core: Extensive updates across the entire frontend compilation pipeline (Lexer, Parser, AST, Resolver, and Typechecker).
Standard Library: Expanded and updated the stdlib (io, path, process, str) to support the new .vyl ecosystem.

Automated Cloud Releases: Added a complete Continuous Integration pipeline using GitHub Actions (release.yml) to automatically build native binaries for Windows, Linux, and macOS (Intel & Apple Silicon).
Developer Scripts: Added PowerShell scripts (build_release.ps1 and bump_version.ps1) to automate version bumping, tagging, and local release packaging.
