Возможность предварительной компиляции скрипта для ускорения запуска

[Bayselonarrend]

Хочу попробовать сделать свою версию #1554 с прекомпиляцией скриптов. Только не автоматическую, а ручную WIP, пока в исследовательских целях)

Summary by CodeRabbit

• New Features
  • Added script precompilation via a new command-line option to produce .osc precompiled scripts.
  • Added execution support for precompiled .osc scripts for faster load/startup.
  • Added ability to persist and restore compiled modules to disk, improving repeatable deployments and tooling.

Walkthrough

Adds MessagePack dependency and module persistence for precompiled runtime modules, a ModuleSerializer for save/load, a CLI "-build" behavior to emit .osc files, a build behavior that compiles and saves modules, an engine overload to create processes from IExecutableModule, and ExecuteScriptBehavior branching to load .osc or source.

Changes

Cohort / File(s)	Summary
Dependency Configuration src/OneScript.Core/OneScript.Core.csproj	Added MessagePack v3.1.4 PackageReference for serialization support.
Module Serialization Infrastructure src/ScriptEngine/Machine/PrecompiledRuntimeModule.cs	Added PrecompiledRuntimeModule (MessagePack-annotated, implements IExecutableModule) and ModuleSerializer with SaveModule() and LoadModule() to persist modules as MessagePack bytes.
Script Engine Integration src/ScriptEngine.HostedScript/HostedScriptEngine.cs	Added public Process CreateProcess(IHostApplication host, IExecutableModule module) overload to initialize engine and create a process directly from an executable module.
CLI Option Registration src/oscript/BehaviorSelector.cs	Registered "-build" command-line option mapped to BuildPrecompiledBehavior.Create.
Build Behavior src/oscript/BuildPrecompiledBehavior.cs	Added BuildPrecompiledBehavior class: compiles source to IExecutableModule, calls ModuleSerializer.SaveModule() to write .osc, returns exit codes and prints ScriptException messages.
Execution Logic src/oscript/ExecuteScriptBehavior.cs	Modified to detect .osc files (case-insensitive): load via ModuleSerializer.LoadModule() and create process from module; otherwise load source and create process from source; each path has its own error handling.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

• Check MessagePack key ordering and compatibility in PrecompiledRuntimeModule.
• Verify ModuleSerializer file I/O error handling and binary integrity.
• Review BuildPrecompiledBehavior compilation path and exception reporting.
• Ensure ExecuteScriptBehavior extension check is case-insensitive and both branches release resources consistently.
• Confirm CreateProcess(IHostApplication, IExecutableModule) mirrors initialization without unintended side effects.

Poem

🐰
I nibbled bytes and packed them neat,
A .osc carrot—oh what a treat!
Save, then load, no parsing fuss,
Hop to run — swift code for us.
A tiny rabbit claps, "Build — let's trust!"

Сделай, пожалуйста, статус черновика в пулреквесте, чтобы было понятно, когда wip закончился

@EvilBeaver Пересоздать его как draft? Или в текущем что-то проставить можно? А, все, нашел
