Update the SendStream interface to match the current Vendor interface
which now uses chan domain.StreamUpdate instead of chan string.
Changes:
- Update SendStream signature to use chan domain.StreamUpdate
- Update sendChatMessageStream signature accordingly
- Update parseSSEStream signature accordingly
- Wrap all channel sends with domain.StreamUpdate{Type: StreamTypeContent}
This fixes the build error introduced when the streaming interface was
updated to support metadata like token usage alongside content.
## CHANGES
- Add Mammouth provider configuration with API base URL
- Configure Mammouth to use standard OpenAI-compatible interface
- Disable Responses API implementation for Mammouth provider
- Add "Mammouth" to VSCode spell check dictionary
Add centralized factory function for AI vendor plugin initialization:
- Add NewVendorPluginBase(name, configure) to internal/plugins/plugin.go
- Update 8 vendor files (anthropic, bedrock, gemini, lmstudio, ollama,
openai, perplexity, vertexai) to use the factory function
- Add 3 test cases for the new factory function
This removes ~40 lines of duplicated boilerplate code and ensures
consistent plugin initialization across all vendors.

Add support for Google Cloud Vertex AI as a provider to access Claude models
using Application Default Credentials (ADC). This allows users to route their
Fabric requests through Google Cloud Platform instead of directly to Anthropic,
enabling billing through GCP.
Features:
- Support for Claude models (Sonnet 4.5, Opus 4.5, Haiku 4.5, etc.) via Vertex AI
- Uses Google ADC for authentication (no API keys required)
- Configurable project ID and region (defaults to 'global' for cost optimization)
- Full support for streaming and non-streaming requests
- Implements complete ai.Vendor interface
Configuration:
- VERTEXAI_PROJECT_ID: GCP project ID (required)
- VERTEXAI_REGION: Vertex AI region (optional, defaults to 'global')
