feat: Add support for OpenRouter (#92)

* Add support for OpenRouter as a new model provider - Introduced `ProviderOpenRouter` in the `models` package. - Added OpenRouter-specific models, including `GPT41`, `GPT41Mini`, `GPT4o`, and others, with their configurations and costs. - Updated `generateSchema` to include OpenRouter as a provider. - Added OpenRouter-specific environment variable handling (`OPENROUTER_API_KEY`) in `config.go`. - Implemented default model settings for OpenRouter agents in `setDefaultModelForAgent`. - Updated `getProviderAPIKey` to retrieve the OpenRouter API key. - Extended `SupportedModels` to include OpenRouter models. - Added OpenRouter client initialization in the `provider` package. - Modified `processGeneration` to handle `FinishReasonUnknown` in addition to `FinishReasonToolUse`. * [feature/openrouter-provider] Add new models and provider to schema - Added "deepseek-chat-free" and "deepseek-r1-free" to the list of supported models in `opencode-schema.json`. * [feature/openrouter-provider] Add OpenRouter provider support and integrate new models - Updated README.md to include OpenRouter as a supported provider and its configuration details. - Added `OPENROUTER_API_KEY` to environment variable configuration. - Introduced OpenRouter-specific models in `internal/llm/models/openrouter.go` with mappings to existing cost and token configurations. - Updated `internal/config/config.go` to set default models for OpenRouter agents. - Extended `opencode-schema.json` to include OpenRouter models in the schema definitions. - Refactored model IDs and names to align with OpenRouter naming conventions. * [feature/openrouter-provider] Refactor finish reason handling and tool call logic in agent and OpenAI provider - Simplified finish reason check in `agent.go` by removing redundant variable assignment. - Updated `openai.go` to override the finish reason to `FinishReasonToolUse` when tool calls are present. - Ensured consistent finish reason handling in both `send` and `stream` methods of the OpenAI provider.

This event was sent upon successful stream completion but is no longer used.
