feat: add Dioxus and GPUI UI prototypes for framework comparison

Browse source 
Dioxus (ui-dioxus/): 2,169 lines, WebView mode (same wry as Tauri),
  Catppuccin theme, 12 components, agor-core integration, compiles clean.
  Evolution path — keeps xterm.js, gradual migration from Tauri.

GPUI (ui-gpui/): 2,490 lines, GPU-accelerated rendering, alacritty_terminal
  for native terminal, 17 files, Catppuccin palette, demo data.
  Revolution path — pure Rust UI, 120fps target, no WebView.

Both are standalone (not in workspace), share agor-core backend.
Created for side-by-side comparison to inform framework decision.

//! agor-gpui: GPU-accelerated Agent Orchestrator UI prototype.
//!
//! Uses Zed's GPUI framework for native GPU rendering.
//! This is a decision-making prototype comparing against the existing Tauri+Svelte app.
//!
//! # Architecture
//!
//! ```text
//! main.rs → Application::new().run()
//! └─ Workspace (root view)
//! ├─ Sidebar (icon rail)
//! ├─ SettingsPanel (drawer, optional)
//! ├─ ProjectGrid
//! │ ├─ ProjectBox[0]
//! │ │ ├─ AgentPane (message list + prompt)
//! │ │ └─ TerminalView (GPU-rendered via alacritty_terminal)
//! │ └─ ProjectBox[1]
//! │ ├─ AgentPane
//! │ └─ TerminalView
//! ├─ StatusBar (bottom)
//! └─ CommandPalette (overlay, optional)
//! ```
//!
//! # Backend Integration
//!
//! `backend.rs` bridges to `agor-core` (PtyManager, SidecarManager) via an
//! `EventSink` that queues events into an mpsc channel. The GPUI main loop
//! drains this channel to update entity state reactively.
//!
//! # Key Differentiator: GPU Terminal
//!
//! `terminal/renderer.rs` uses `alacritty_terminal::Term` for VT100 parsing
//! and renders each cell directly via GPUI's text pipeline — no DOM, no
//! Canvas 2D context, just GPU-accelerated glyph rendering.

//
// let backend = Backend::new();
// cx.spawn(|cx| async move {
// loop {
// Timer::after(Duration::from_millis(16)).await; // ~60fps
// let events = backend.drain_events();
// for ev in events {
// // Route to appropriate entity updates
// }
