//! GitHub forge backend for travelagent.
//!
//! Implements [`travelagent_core::forge::ForgeBackend`] against the
//! GitHub REST + GraphQL APIs. Handles both github.com and GitHub
//! Enterprise; authentication resolves from `GITHUB_TOKEN` / `GH_TOKEN`
//! / `gh auth token` in that order.
//!
//! The public entry point is [`GitHubForge`], constructed via
//! `GitHubForge::new()` (which resolves the token up-front) and
//! passed to the TUI or MCP crates via the
//! [`travelagent_core::forge::ForgeBackend`] trait.
// Fields exist for serde deserialization, not direct access
