merge: cliente web + móvil de unibus

SPA de chat (web/, React+Vite+Mantine v9) contra el gateway, y app Android
nativa (android/, Kotlin+Compose) sobre el binding gomobile, con E2E en el
dispositivo. Amplía el binding (Card/Invite/Kick) y el gateway (rooms/members
+ CORS). Verificado end-to-end: chat cifrado en vivo entre dos pestañas web y
envío/recepción en el AVD Pixel_API34. Ver reports/0002.

# unibus · app Android
Cliente móvil nativo de unibus. La app no habla con un gateway: embebe un **peer
real** del bus a través del binding gomobile `mobile/unibus.go`, de modo que el
cifrado extremo a extremo corre **en el dispositivo**. Cada teléfono es un peer
de primera clase del bus, igual que cualquier peer Go.
## Arquitectura
```
Kotlin/Compose UI ──> BusViewModel ──> com.unibus.core.mobile.Session (.aar)
│ (NATS data plane + E2E crypto, en Go)
membershipd (control plane HTTP :8470)
NATS (data plane :4250)
```
- `BusViewModel` traduce intents de UI en llamadas al binding. Las llamadas de red
(`newSession`, `createRoom`, `join`, `publish`) corren en `Dispatchers.IO`.
- Los frames entrantes llegan por `FrameListener.onFrame` en una goroutine NATS
(hilo JNI); se publican en un `StateFlow` (thread-safe) que Compose recolecta en
el hilo principal.
## Requisitos
- Android SDK (compileSdk 34), NDK (para regenerar el `.aar`), JDK 17.
- El binding `app/libs/unibus.aar` (no versionado: es un artefacto de ~24 MB).
## 1. Generar el binding (.aar)
Desde la raíz del repo de la app (`projects/message_bus/apps/unibus`):
```bash
export ANDROID_HOME=$HOME/android-sdk
export ANDROID_NDK_HOME=$HOME/android-sdk/ndk/26.3.11579264
mkdir -p android/app/libs
gomobile bind -target=android -androidapi 21 -javapkg com.unibus.core \
-o android/app/libs/unibus.aar ./mobile
```
Esto produce `unibus.aar` con la clase estática `com.unibus.core.mobile.Mobile`
(`generateIdentity`, `newSession`) y los tipos `Session` y `FrameListener`.
## 2. Compilar el APK
```bash
cd android
export JAVA_HOME=$HOME/android-sdk/jdk-17/jdk-17.0.19+10
export ANDROID_HOME=$HOME/android-sdk
./gradlew assembleDebug
# APK: app/build/outputs/apk/debug/app-debug.apk
```
`local.properties` apunta a `sdk.dir`; ajústalo si tu SDK está en otra ruta.
## 3. Arrancar el bus y probar en el emulador
```bash
# 1. En el PC: control plane + NATS embebido (HTTP :8470, NATS :4250)
cd projects/message_bus/apps/unibus && go run ./cmd/membershipd
# 2. Emulador Pixel_API34
$ANDROID_HOME/emulator/emulator -avd Pixel_API34 &
# 3. Instalar + lanzar
adb install -r app/build/outputs/apk/debug/app-debug.apk
adb shell am start -n com.unibus.app/.MainActivity
```
En la pantalla de conexión, desde el emulador el host del PC es `10.0.2.2`:
- **Host (control plane):** `http://10.0.2.2:8470`
- **NATS (data plane):** `nats://10.0.2.2:4250`
Para un teléfono físico en la misma LAN, usa la IP LAN del PC en lugar de
`10.0.2.2`.
## Notas
- La identidad del peer se guarda en `filesDir/peer.id` (claves privadas
Ed25519 + X25519). No se sincroniza ni se respalda.
- Una room creada en modo "cifrar (E2E)" usa la política Matrix (cifrada,
persistida, firmada); en modo normal usa NATS cleartext.

# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
