nomoreide-daemon 0.20.4

//! What the agents have spent: the current reading, and the history of it.
//!
//! Both routes are exact, so a wrong method falls through to the SPA shell's
//! 404 rather than answering 405.
//!
//! **The working directory is part of the answer.** Claude Code keys its
//! per-project totals by absolute path, so `/api/agent/usage` reports the
//! directory the daemon was started in — not the selected repository, which is
//! a different thing that a user can change without restarting anything.
