feat(explorer+daemon): discovery dinamico via broker + query socket
Cierra el "explorer encuentra al daemon de forma totalmente dinamica"
del meta-plan. La UI deja de hardcodear el socket admin: descubre al
daemon nouser via MatchEvent::Available del broker y le consulta sus
Monadas directo.
Pipeline end-to-end:
- Daemon publica engine Card con service_socket = $XDG_RUNTIME_DIR/
nouser-engine.sock y flow.output = monad-list:json.
- Daemon binda Unix socket en ese path con listener blocking que
sirve nouser_card::query::QueryRequest::ListMonads, responde
ListMonadsResponse { engine, monads: Vec<MonadView> }.
- Explorer construye consumer Card con flow.input matched,
brahman_sidecar::await_provider_blocking le devuelve el socket,
y nouser_core::engine_socket::client::list_monads lo consulta.
- Cachea el socket; cualquier fallo de query lo invalida y la
proxima iteracion re-descubre.
Wire types nuevos en nouser_card::query:
- QueryRequest::ListMonads
- ListMonadsResponse { engine: EngineInfo, monads: Vec<MonadView> }
- MonadView: proyeccion slim de MonadManifest SIN centroid ni
members (KB que no tienen por que viajar cada poll).
- transport::default_socket_path() con env override.
Listener en nouser_core::engine_socket: spawn_listener + client
blocking con QueryError tipado. 3 tests integracion verdes.
Refactor explorer:
- Drop dep brahman-admin, add brahman-sidecar/nouser-card/nouser-core.
- State: socket cache + snapshot + socket_source informativo.
- TickOutcome enum desacopla la I/O del UI.
Trade-offs: polling 2s (no streaming — broker no empuja Data cards
hoy), re-discovery full en error (discovery es barato).
Tests: 10 (nouser-card +3 query) + 27 (nouser-core +3 engine_socket)
+ 4 (sidecar) verdes. Explorer compila clean.

+### feat(explorer+daemon): discovery dinámico vía broker + query socket
+La UI deja de hardcodear el socket admin: ahora descubre al daemon
+nouser vía `MatchEvent::Available` del broker brahman y le consulta
+sus Mónadas directo, sin pasar por brahman-admin. Cierra el "explorer
+encuentra al daemon de forma totalmente dinámica" del meta-plan.
+
+Pipeline end-to-end:
+- Daemon publica engine Card con `service_socket = $XDG_RUNTIME_DIR/nouser-engine.sock`
+ y `flow.output = monad-list:json`.
+- Daemon binda un Unix socket en ese path y monta un listener
+ blocking que sirve `nouser_card::query::QueryRequest::ListMonads`,
+ responde `ListMonadsResponse { engine, monads: Vec<MonadView> }`.
+- Explorer construye un consumer Card con `flow.input = monad-list:json`
+ vía `brahman_sidecar::build_consumer_card`, llama
+ `await_provider_blocking(card, 3s)` y recibe el socket descubierto.
+- Cachea ese socket; cada poll (2s) llama
+ `nouser_core::engine_socket::client::list_monads(socket, 2s)`.
+ Fallo de query → invalida cache → próximo tick re-descubre.
+
+Wire types nuevos en `nouser_card::query`:
+- `QueryRequest::ListMonads` (single variant por ahora).
+- `ListMonadsResponse { engine: EngineInfo, monads: Vec<MonadView> }`.
+- `MonadView`: proyección slim de `MonadManifest` SIN `centroid` ni
+ `members` — la UI no los necesita y eran KB por Mónada que no
+ tenían por qué viajar cada poll.
+- `transport::default_socket_path()` con env override
+ `NOUSER_ENGINE_SOCKET`.
+- Const `FLOW_MONAD_LIST = "monad-list"`, `FLOW_TYPE_NAME = "json"`.
+
+Listener en `nouser_core::engine_socket`:
+- `spawn_listener(config, db)` arma std::os::unix::net::UnixListener
+ en thread blocking dedicado. Frecuencia esperada (UI cada 2s) no
+ amerita tokio.
+- `client::list_monads(socket, timeout)` — cliente blocking con
+ `QueryError` tipado (Connect / Io / Serde / Daemon / Timeout / Empty).
+- 3 tests integración: roundtrip vacío, Mónadas reales, request
+ inválido devuelve ErrorResponse.
+
+Refactor explorer:
+- Drop dep `brahman-admin`, add deps `brahman-sidecar`, `nouser-card`,
+ `nouser-core`.
+- State: `socket: Option<PathBuf>` cache + `snapshot: Option<ListMonadsResponse>`
+ + `socket_source: "discovery"|"cache"` (sólo informativo).
+- Tick: `tick(prior_socket)` separado del UI, devuelve un enum
+ `TickOutcome::{Ok, DiscoveryFailed, QueryFailed}`. Cualquier
+ fallo invalida la cache → re-discovery automática.
+- Header reformulado: `Engine 'nouser_engine' · N mónada(s) ·
+ socket: /... (cache|discovery) · watching: /tmp/x`.
+- Render pintado de un engine card + Mónadas, sin ya iterar
+ `BrokeredCard` del admin.
+
+Trade-offs aceptados:
+- Polling 2s (no streaming). El broker no empuja cambios de Data
+ cards hoy; agregar streaming requiere extender el protocolo
+ handshake. Para snapshot UI, polling 2s es suficiente.
+- Re-descubrimiento full en cada error de query (en lugar de retry
+ con backoff). Discovery es barato (~ms vs broker), no vale la
+ pena la complejidad.
+
+Tests: 10 (nouser-card, +3 query) + 27 (nouser-core, +3 engine_socket)
++ 4 (sidecar) verdes. Explorer compila clean.
