feat: Weevil v1.0.0-beta1 - FTC Project Generator

Cross-platform tool for generating clean, testable FTC robot projects
without editing the SDK installation.

Features:
- Standalone project generation with proper separation from SDK
- Per-project SDK configuration via .weevil.toml
- Local unit testing support (no robot required)
- Cross-platform build/deploy scripts (Linux/macOS/Windows)
- Project upgrade system preserving user code
- Configuration management commands
- Comprehensive test suite (11 passing tests)
- Zero-warning builds

Architecture:
- Pure Rust implementation with embedded Gradle wrapper
- Projects use deployToSDK task to copy code to FTC SDK TeamCode
- Git-ready projects with automatic initialization
- USB and WiFi deployment with auto-detection

Commands:
- weevil new <name> - Create new project
- weevil upgrade <path> - Update project infrastructure
- weevil config <path> - View/modify project configuration
- weevil sdk status/install/update - Manage SDKs

Addresses the core problem: FTC's SDK structure forces students to
edit framework internals instead of separating concerns like industry
standard practices. Weevil enables proper software engineering workflows
for robotics education.
