claude-hindsight 2.4.0

//! Implementation of the `daemon` command
//!
//! Starts a minimal background HTTP listener (default port 7228) that
//! accepts OTLP http/json payloads and stores them in the Hindsight database.
//! When auto-spawned by the SessionStart hook, uses an idle timeout so the
//! daemon exits cleanly after a period of inactivity.
