Add Inception Labs provider (mercury-2) for Agent Zero

[Raleksand]

Overview

This pull request adds a new Inception Labs LLM provider plugin for Agent Zero. The provider offers the mercury-2 model via the OpenAI‑compatible API endpoint https://api.inceptionlabs.ai/v1.

Files added

• usr/plugins/_inception_provider/plugin.yaml – plugin manifest (title, description, version, always_enabled).
• usr/plugins/_inception_provider/conf/model_providers.yaml – provider configuration (chat provider inception, LitLLM provider openai, model list, api_base).
• usr/plugins/_inception_provider/README.md – installation and usage instructions (English).
• usr/plugins/_inception_provider/LICENSE – MIT license (or your chosen open‑source license).

Required secret

The plugin expects an environment variable / secret named INCEPTION_API_KEY. Users must add this secret in their Agent Zero instance (e.g., via the UI or a0-manage-plugin set-secret). The key is not stored in the repository.

How to use

1. Place the _inception_provider folder under usr/plugins/ of the Agent Zero installation.
2. Restart Agent Zero (or reload providers) so the new provider appears in the UI.
3. In Settings → Model Configuration, select Inception Labs as the chat provider and set the model to mercury-2.
4. The provider will automatically use the INCEPTION_API_KEY secret.

Testing

The plugin was tested locally with the Cost Efficient preset and the mercury-2 model. All calls succeeded and returned expected responses.

Notes

• No runtime dependencies beyond the existing Agent Zero core.
• The plugin follows the standard Agent Zero plugin structure and passes the a0-manage-plugin validate checks.
• No API keys or other secrets are included in the repository.

Please review the code, run the CI checks, and merge if everything looks good.
