Render the full-screen session list as the TUI's home screen.

## Layout

```
┌─ Sessions ──────────────────────────────────────────────────────┐
│ ID       Date                 Project              Model    Msgs Agents │
│ ────────────────────────────────────────────────────────────────────── │
│ 21fae0a8 2026-03-29 14:32:01 …/pop/claudbg         claude-3   42    3  │◄ selected (highlighted)
│ def4776b 2026-03-28 10:15:44 …/pop/claudbg         claude-3  128    1  │
│ ...                                                                     │
└─────────────────────────────────────────────────────────────────┘
```

## Implementation

- Use `ratatui::widgets::Table` with `TableState` for selection tracking.
- Highlight the selected row with a `Style` that inverts colors or uses a distinct background.
- Columns: ID (8), Date (20), Project (dynamic, truncated to tail), Model (20), Msgs (6), Agents (7).
- Project path: display only the last 30 or so characters (prefix with `…`).
- Populate from `AppState.sessions` (loaded on TUI start from `discover_sessions` + DB).
- Scroll with arrow keys / j/k; selected index tracked in `AppState.list_selected`.
