Rename to entropymon, restructure as PyPI package

- Renamed systats -> entropymon everywhere (code, logo, config paths)
- New ASCII art logo: ENTROPY MON
- Proper Python package structure: entropymon/{__init__,__main__,monitor}.py
- pyproject.toml with entry_points (pip install -> entropymon command)
- MIT license, README with full docs
- Works: pip install, entropymon CLI, python -m entropymon
- Optional nvidia extra: pip install entropymon[nvidia]
- --version flag added

+# entropymon
+
+**Terminal system monitor by Electric Entropy Lab**
+
+A powerful, feature-rich terminal system monitor built with Python curses. Better than glances, prettier than htop.
+
+## Features
+
+- **CPU** - per-core usage bars, sparkline history, frequency, load average
+- **Memory** - RAM/Swap with usage bars
+- **Disk** - partitions with usage, IO rates (read/write)
+- **Network** - RX/TX rates with sparklines, per-interface info
+- **GPU** - NVIDIA (via NVML) and AMD (via sysfs) - utilization, VRAM, temp, power, fan, clocks
+- **Temperatures** - CPU, GPU, NVMe, network adapters
+- **Processes** - interactive management with sorting, filtering, kill signals, renice, details
+- **Multi-language** - EN, PL, DE, ES, FR, UK, ZH with runtime switching
+- **Animated intro** - matrix rain boot sequence with decrypt logo animation
+
+## Install
+
+```bash
+pip install entropymon
+```
+
+With NVIDIA GPU support:
+
+```bash
+pip install entropymon[nvidia]
+```
+
+## Usage
+
+```bash
+entropymon                 # start with auto-detected language
+entropymon --lang pl       # start in Polish
+entropymon --no-intro      # skip boot animation
+entropymon --reset-lang    # reset saved language preference
+entropymon --version       # show version
+```
+
