`GET /api/info` now carries `build` (commit hash, commit date, dirty flag) and `instance`, a fresh uuid per daemon process. Together they let a client name the release it is talking to and, after losing its socket, tell an upgrade from a plain restart from a network blip. The stamp comes from `maestro-daemon/build.rs`, which reads the git checkout it compiles in. The Nix build has no `.git` in the crane-filtered source, so `flake.nix` passes the flake's own revision and last-modified date through `MAESTRO_BUILD_*` instead. Neither available leaves the fields empty. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

//! What release this daemon is, and which run of it.

|
|
//! Two facts ride `GET /api/info` so clients can render a status indicator and
|
|
//! survive an upgrade:
|
|
//!
|
|
//! * [`build_info`] — the commit the binary was compiled from, stamped by
|
|
//! `build.rs`. Shown in the indicator's tooltip; a change across a reconnect
|
|
//! means the operator upgraded, so a browser reloads its assets.
|
|
//! * [`instance_id`] — a fresh id per daemon process. A change with the same
|
|
//! commit means a plain restart, which clients ride out silently.
