Redstone NBT v1.0.1 — Fix file opening via double-click / CLI

🐛 Bug Fixes

- **File Associations & Double-Click**: Fixed an issue where launching Redstone NBT by double-clicking a `.dat`, `.mca`, or `.nbt` file in the file manager only opened the application window without loading the file.             
- **Auto-Expansion**: Files and folders opened from the file manager now automatically expand their root elements for immediate inspection.
- **About Dialog**: Added version tag display to the About window.

Redstone NBT v1.0.0 — Modern Minecraft NBT Editor

🎉 Redstone NBT v1.0.0

Redstone NBT is a modern, high-performance Minecraft NBT and region file editor for Linux, Windows, and macOS, directly rejuvenated from Justin Aquadro's classic NBTExplorer.

### ✨ Highlights
- **Authentic NBTExplorer Tag Ordering**: Containers (Compounds, Lists) grouped first, followed by scalars and arrays.
- **View Sorting Modes**: Group Containers First (Default), Alphabetical (A to Z), Tag Type, or File Order.
- **Drag & Drop**: Drop single/multiple NBT files, region files (.mca/.mcr), or world folders directly onto the window.
- **Inline In-Place Editing**: Press Enter or click scalar values to edit directly in the tree without popups.
- **Universal Format Support**: Java McRegion/Anvil (up to 1.21+), Structure NBT, Schematics, and Bedrock Little-Endian structures.
- **Multi-Architecture**: Native 64-bit builds for both x86_64 and ARM64.
