# Scenario 1: Implement a Ruby Optimizer Handler

## Context

The codeflash-internal monorepo currently supports Python and JavaScript/TypeScript optimization through the multi-language handler system. The team wants to add Ruby as a new supported language for the optimizer feature. The handler should integrate with the existing registry, dispatcher, and router systems.

The relevant existing code lives in:
- `django/aiservice/core/languages/` (per-language handlers)
- `django/aiservice/core/registry.py` (LanguageRegistry, @register_handler)
- `django/aiservice/core/dispatcher.py` (get_handler_for_feature, Feature enum)
- `django/aiservice/core/protocols/` (OptimizerProtocol, LanguageHandler)
- `django/aiservice/core/shared/optimizer_router.py` (shared router that dispatches by language)

## Task

1. Create a new Ruby optimizer handler at `django/aiservice/core/languages/ruby/optimizer/optimizer.py` that:
   - Registers itself using the `@register_handler("ruby")` decorator
   - Sets `supports_optimizer = True` and other `supports_*` flags to `False`
   - Implements `OptimizerProtocol` with an `optimizer_optimize(request, data)` async method
   - Uses `ninja.Schema` for any request/response models
   - Calls LLM through the proper abstraction layer
   - Stores the optimization prompt as a `.md` file alongside the module, rendered with Jinja2

2. Add the Ruby language routing in `core/shared/optimizer_router.py` using lazy imports with the `# noqa: PLC0415` suppression

3. Import the Ruby handler module in `core/languages/__init__.py` so the decorator fires at startup

4. Create a basic test file at `django/aiservice/tests/optimizer/test_ruby_optimizer.py`

## Expected Outputs

- `core/languages/ruby/__init__.py`
- `core/languages/ruby/optimizer/__init__.py`
- `core/languages/ruby/optimizer/optimizer.py` — handler class with decorator, protocol, async method
- `core/languages/ruby/optimizer/optimize_prompt.md` — Jinja2 prompt template
- Updated `core/shared/optimizer_router.py` — lazy import dispatch for "ruby"
- Updated `core/languages/__init__.py` — import of ruby module
- `tests/optimizer/test_ruby_optimizer.py` — async test with @pytest.mark.asyncio
