feat: add web UI for editing configuration

## Problem `archforge-optimizer init` currently generates scaffold files that users need to edit manually in Python. For someone who is new to ArchForge, understanding which values to change and where to change them can be harder than necessary. The generated files also rely on code comments to explain configuration and usage. ## Proposed solution Add a simple web-based UI for editing the scaffolded ArchForge project. The UI should provide a visual interface for configuring the generated project instead of requiring users to directly edit the scaffold code and configuration files. Users should be able to: - View the current scaffold configuration - Edit relevant ArchForge settings through forms/controls - Configure the optimization tasks/suite - Configure the adapter and seed/spec settings - Save the changes back to the scaffold files - See the resulting configuration before saving The goal is not to hide the underlying files, but to provide an easier entry point for users who don't want to manually navigate through generated code and comments. ## Example workflow ```text archforge-optimizer init ↓ open ArchForge UI ↓ edit project configuration ↓ save ↓ scaffold files updated ↓ archforge-optimizer evolve
