PR Summary

Low Risk
Incremental CLI configuration with tests; no changes to runtime auth or app request handling beyond env key registration for setup tooling.

Overview
Adds npx sim-setup add chat so operators can set or replace the Chat API key without rerunning the full wizard, alongside updates to CLI help and README examples.

The chat path prompts for COPILOT_API_KEY, applies SIM_AGENT_API_URL (mothership override) and NEXT_PUBLIC_CHAT_DISABLED via existing wizard helpers, and writes through reconcileEnvValues to the detected install (e.g. Compose .env). If no key is provided, setup throws and leaves configuration unchanged.

Chat is registered as a setup feature but omitted from sim-setup config capability ordering (same pattern as OAuth integrations). DEPLOYMENT_CONFIGURATION_KEYS now includes the chat-related env vars so discovery and shell-shadowing logic treat them as managed deployment config. sim-setup is bumped to 1.0.2.
