feat(console): add Artemis Admin & Trace Console backend and management plane

Introduces the comprehensive developer/administrator control plane and trace
inspection console backend for the ARTEMIS mobile automation platform.

Key Features & Backend Architecture:
- Core Server & Modular Routing:
  * FastAPI modular architecture with dedicated routers for sessions, steps, tasks, media, stream, and replay.
  * Multi-layer repository pattern with SQLite persistence for sessions, traces, and step data.
- Task Control & Queue Management:
  * FIFO asynchronous task queue service with support for single/batch goal execution and profile selection (Flash / Pro).
  * Session lifecycle controls (run, pause, resume, stop, clear queue).
  * Startup orphan cleanup and automatic older replay archiving.
- Live Telemetry & IPC Communication:
  * High-performance IPC server for streaming real-time execution logs, agent thoughts, and tool invocations.
  * Server-Sent Events (SSE) /api/stream/{session_id} endpoint for live UI updates.
- Real-Time Device Streaming:
  * Live ADB screen capture and MJPEG frame generator (/api/stream/device-live).
  * Device connectivity and state inspection endpoint (/api/stream/device-state).
- Trace Inspection & Step Replay Engine:
  * Hierarchical call tree inspection, pre/post step screenshots, and action overlay metadata.
  * Isolated single-step replay manager (/api/replay) for interactive debugging and validation.

+# 🛠️ Artemis Admin & Trace Console
+
+A comprehensive developer/administrator control plane and trace inspection console for the Latte/Artemis mobile automation system.
+
+---
+
+## 🎯 Key Features
+
+1. **Full Trace Inspection (`/api/sessions`, `/api/steps`)**:
+   - Hierarchical Call Tree exploration (LLM thoughts, tool calls, agent motivations).
+   - Step-by-step pre/post screenshots and action overlays (tap circles, swipe paths).
+   - Streaming logs and video recording playback.
+2. **Task Control Center (`/api/run`)**:
+   - Directly launch autonomous tasks with custom goals and model profiles (Flash / Pro).
+   - Pause, resume, and manage FIFO task execution queues.
+3. **Step Replay & Debugging Engine (`/api/replay`)**:
+   - Replay individual steps with isolated inputs, state inspection, and live device execution.
+

+
+## 🚀 How to Start
+
+### Option 1: Using `uv` (Recommended)
+From the repository root:
+```bash
+uv run uvicorn apps.admin_console.server:app --host 0.0.0.0 --port 8000 --reload
+```
+Or directly using Python module:
+```bash
+uv run python -m apps.admin_console.server
+```
+
+### Option 2: From the `apps/admin_console` directory
+```bash
+cd apps/admin_console
+uv run uvicorn server:app --host 0.0.0.0 --port 8000 --reload
+```
+
+Once started, open your browser and navigate to:
+👉 **`http://localhost:8000`**
+
+---
+
+## 🎥 Video Debugging Mode
+
+By default, `VideoAnalyzer` cleans up local temporary video files after execution. To retain video recordings for full playback in the console:
+
+```bash
+KEEP_VIDEOS=1 artemis run "your task goal"
+```
+Or set `ARTEMIS_DEBUG=1` in your environment.
