Use agent platforms with Subconscious

Set up the agent platform I use to run on Subconscious as its model provider.

Subconscious is an inference API for agents. It serves open models through OpenAI- and Anthropic-compatible endpoints, billed per token.
- OpenAI-compatible base URL: https://api.subconscious.dev/v1
- Anthropic-compatible base URL: https://api.subconscious.dev
- Model: subconscious/glm-5.3-marathon
- API key: read it from the SUBCONSCIOUS_API_KEY environment variable. Never commit the key or paste it into project files. If it is not set, ask me to create one at https://platform.subconscious.dev.

Work out which of these tools I am using: check my project and installed tools, or ask me. Then fetch its setup guide and follow it. Each guide is Markdown and lists every command and config file.

Agent platforms:
- Coder: https://www.subconscious.dev/agents/platforms/coder.md
- Kodus: https://www.subconscious.dev/agents/platforms/kodus.md
- Conductor: https://www.subconscious.dev/agents/platforms/conductor.md

If you cannot fetch URLs, point the tool at the OpenAI-compatible base URL with the model above, or ask me for the guide.

When you are done, confirm the tool is using subconscious/glm-5.3-marathon, then summarize what you changed.
