James Rich 39333b3bea feat(ui): implement draggable pane expansion in adaptive navigation
This commit enhances the adaptive navigation system by adding draggable dividers to the list-detail and supporting pane layouts. This allows users to manually resize panes in multi-pane "Power User" scenes on larger displays.

Specific changes include:
- **Navigation Enhancements**: Updated `MeshtasticNavDisplay` to include `rememberPaneExpansionState` and `VerticalDragHandle` within `ListDetailSceneStrategy` and `SupportingPaneSceneStrategy`.
- **UI Components**: Configured `paneExpansionDraggable` modifiers with a minimum touch target of 48.dp for improved accessibility.
- **Documentation**: Updated `AGENTS.md` to reflect the availability of draggable dividers (`VerticalDragHandle` + `paneExpansionState`) for widths ≥ 1200dp.
- **Code Style**: Applied consistent formatting and line-wrapping across `NavBackStackExt.kt`, `MeshtasticAppShell.kt`, `ContactsNavigation.kt`, and `MeshtasticNavigationSuite.kt`.

Overview

The :feature:messaging module handles the core communication features of the app, including text messages, direct messages (DMs), and channel-based chat.

Key Components

1. MessageViewModel

Manages the state of the chat screen, including loading messages from the database, sending new messages, and handling message reactions.

2. QuickChat

A simplified chat interface for quickly sending and receiving messages without entering the full message screen.

3. HomoglyphCharacterStringTransformer

A security-focused utility that detects and transforms homoglyphs (visually similar characters from different scripts) to prevent phishing and impersonation attacks.

Features

  • Channel Chat: Group communication on public or private channels.
  • Direct Messaging: One-on-one encrypted communication between nodes.
  • Message Reactions: Support for reacting to messages with emojis.
  • Delivery Status: Indicators for "Sent", "Received", and "Read" (ACK/NACK).
