## Description
Documents the new TLS listener support for AI Bridge Proxy.
Updates `setup.md` with a new "Proxy TLS Configuration" section covering self-signed and corporate CA certificate setup, rewrites "Security Considerations" to reflect TLS as the recommended approach for encrypting client connections, and updates "Client Configuration" with `HTTPS_PROXY` defaults and combined certificate trust instructions.
Updates `copilot.md` to default all proxy URL examples to `https://`, add TLS certificate trust guidance for each client (CLI, VS Code, JetBrains), and document the MCP server trust store requirement for Copilot CLI.
Closes: https://github.com/coder/internal/issues/1335
