feat: add template migration to CLI (#880)
## 🔄 Add Template Migration to CLI
### Summary
This PR introduces a new `migrate` command to the E2B CLI that helps
users transition from the legacy Dockerfile + TOML configuration format
to the new Template SDK format. The migration tool automatically
converts existing `e2b.Dockerfile` and `e2b.toml` configurations into
SDK-compatible template files using Handlebars templates.
### What's Changed
#### ✨ New Features
- **Template Migration Command**: Added `e2b template migrate` command
for converting legacy configurations to SDK format
- **Multi-Language Support**: Supports migration to TypeScript, Python
(sync), and Python (async) formats
- **Interactive Language Selection**: CLI prompts for target language
when not specified
- **Multi-stage Dockerfile Support**: Added fallback handling for
complex multi-stage Dockerfiles
#### 🔧 Technical Improvements
- **Enhanced ENV Handling**: Improved parsing of multiple environment
variables from single ENV instructions
- **File Name Conflict Resolution**: Automatic unique filename
generation to prevent overwriting existing files
- **Comprehensive Template Generation**: Creates both development and
production build files
#### 📁 New Template Files
- `typescript-template.hbs` - TypeScript template generation
- `typescript-build.hbs` - TypeScript build script template
- `python-template.hbs` - Python template generation (supports both
sync/async)
- `python-build-async.hbs` - Python async build script template
- `python-build-sync.hbs` - Python sync build script template
### Usage
```bash
# Migrate with interactive language selection
e2b template migrate
# Migrate to specific language
e2b template migrate --language typescript
e2b template migrate --language python-sync
e2b template migrate --language python-async
# Custom paths
e2b template migrate --dockerfile custom.dockerfile --config custom.toml
```
### Generated Output
The migration command generates three files per target:
- `template.{ts|py}` - Template definition using SDK
- `build{.|_}dev.{ts|py}` - Development build script
- `build{.|_}prod.{ts|py}` - Production build script
### Migration Process
1. **Parse Configuration**: Reads `e2b.toml` for template settings
2. **Dockerfile Analysis**: Uses E2B SDK to parse Dockerfile
instructions
3. **Transformation**: Converts Docker instructions to SDK method calls
4. **Code Generation**: Uses Handlebars templates to generate target
language files
5. **File Creation**: Writes template and build files with conflict
resolution
### Error Handling
- **Graceful Dockerfile Parsing**: Falls back to custom image reference
for unparseable Dockerfiles
- **Clear User Guidance**: Provides manual build instructions when
automatic conversion fails
- **Validation**: Ensures required configuration files exist before
