Add CMake wrapper for native CLion integration with PlatformIO

- Create CMakeLists.txt that wraps PlatformIO commands as CMake targets
- Remove CMakeLists.txt from .gitignore to track the wrapper
- Update CLION_BUILD.md with UI-based build instructions
- Provides build targets: pio_build, pio_clean, pio_upload, pio_monitor
- Adds per-environment targets: build_tasmota, build_tasmota32, etc.
- Includes source indexing for CLion code intelligence

Now you can build directly from CLion's UI using the build dropdown
and hammer icon instead of terminal commands.

+PlatformIO CLI has been installed and a CMake wrapper has been configured to integrate PlatformIO with CLion's native build system.

+## Building from CLion UI
+
+CLion will now show PlatformIO targets in the build configurations dropdown:
+
+- **pio_build** - Build the default environment (tasmota)
+- **pio_clean** - Clean build files
+- **pio_upload** - Upload firmware to device
+- **pio_monitor** - Open serial monitor
+- **build_tasmota** - Build tasmota environment
+- **build_tasmota32** - Build tasmota32 environment
+- **build_tasmota-minimal** - Build minimal environment
+- **build_tasmota-sensors** - Build with sensors
+- **build_tasmota-display** - Build with display support
+- **build_tasmota-ir** - Build with IR support
+- **generate_compile_commands** - Update code intelligence
+
+Simply select a target from the dropdown and click the Build button (hammer icon) or press Ctrl+F9.

-## Notes
+## How It Works
 
-- CLion will use CMake for code indexing, but actual builds use PlatformIO
+The `CMakeLists.txt` file is a wrapper that:
-- The CMakeLists.txt files are for ESP-IDF builds (alternative build system)
+- Defines custom CMake targets that invoke PlatformIO commands
-- For this project, always use `pio` commands for building
+- Provides source file indexing for CLion's code intelligence
+- Integrates PlatformIO with CLion's native build system
+- Allows you to use CLion's build UI instead of terminal commands
+
+The actual compilation is still done by PlatformIO, but CLion can manage it through the CMake interface.
