feat(ui): Add Interactive TUI Dashboard (Cyberpunk Financial Terminal)

[sjhddh]

Summary

FinRobot is a powerful brain, but it lacks a face. This PR introduces a Cyberpunk Financial Terminal - a high-aesthetic TUI (Terminal User Interface) that provides a "Mission Control" interface for observing Agent behavior in real-time.

Built with Textual, 100% Python, highly responsive.

The Problem

Currently, FinRobot agents output logs to the console or static files. While functional, this approach:

• Makes it difficult to observe agent decision-making in real-time
• Provides no visual feedback on market data or signals
• Lacks the "wow factor" for demonstrations and showcases

The Solution

A Bloomberg Terminal meets Cyberpunk 2077 interface featuring:

Visual Components

Panel	Description
Ticker Bar	Scrolling marquee with live stock prices (NVDA, AAPL, BTC, etc.)
Market Watch	ASCII sparkline chart + key metrics (P/E, RSI, MACD, Volume)
Neural Stream	Agent's chain-of-thought with categorized, timestamped logs
Signal Panel	Bold BUY/SELL/HOLD cards with confidence bars

Key Features

• Demo Mode: Run with --demo flag for realistic simulated data streams
• Real Agent Integration: AgentDataInterface class ready for plugging into real FinRobot agents
• Keyboard Controls: Pause/resume stream, refresh display, quit
• Cyberpunk Aesthetic: Neon green, amber, cyan on deep black background

Usage

# Install dependencies
pip install textual rich

# Run in demo mode (simulated data)
python finrobot_terminal_ui.py --demo

Keyboard Shortcuts

Key	Action
q	Quit
Space	Pause/Resume stream
r	Refresh display

Integration with FinRobot Agents

from finrobot_terminal_ui import FinRobotTerminal, AgentDataInterface

# Create interface
interface = AgentDataInterface()

# In your agent code, push data:
interface.push_thought("STRATEGY", "Detected bullish divergence")
interface.push_signal("BUY", 0.85)
interface.push_price("NVDA", 145.50, change_pct=1.2)

# Launch TUI with interface
app = FinRobotTerminal(data_interface=interface)
app.run()

Files Changed

• finrobot_terminal_ui.py - New file (main TUI implementation, ~900 lines)
• requirements.txt - Added textual>=0.47.0 and rich>=13.7.0

Test Plan

• Verify syntax: python -m py_compile finrobot_terminal_ui.py
• Run demo mode: python finrobot_terminal_ui.py --demo
• Test keyboard controls (q, Space, r)
• Verify no breaking changes to existing functionality
