Renamed `AppConfig` to `Runtime` and updated method names for clarity, replacing `new` with `configure`. Adjusted `main.rs` to use the revised `Runtime` struct and method, simplifying server initialization and aligning terminology.
Eliminated `session_identify.rs` and related session-based logic to streamline the codebase. Refactored webhooks routes to use `agent_id` instead of `stream_id` for improved clarity. Adjusted configuration and dependencies to align with these changes.
Revised comments for clarity in main.rs and session_identify.rs. Included an explanatory note about using third-party hosts for signature verification. Removed an unused `.toak-ignore` file.
