/**
 * Configuration constants for the Factory Droid provider.
 *
 * Factory is a session-based agent orchestration API — NOT OpenAI-compatible.
 * All provider behavior (base URL, env var names, poll timing, computer
 * auto-creation) is pinned here so the client, stream engine, and tests share
 * a single source of truth.
 *
 * Wire model (verified against docs.factory.ai/api-reference and the
 * @factory/droid-sdk REST helpers):
 *
 *   POST /api/v0/sessions                    → create session (computerId required)
 *   POST /api/v0/sessions/{id}/messages      → fire-and-forget user message
 *   GET  /api/v0/sessions/{id}               → status (idle|pending|running) + tokenUsage
 *   GET  /api/v0/sessions/{id}/messages?role=assistant → assistant content blocks
 *   POST /api/v0/sessions/{id}/interrupt     → stop a running agent loop
 *   GET  /api/v0/computers                   → list computers
 *   POST /api/v0/computers                   → create computer (provider e2b / byom)
 *   GET  /api/v0/machines/templates          → list cloud machine templates
