- Add notify_error function to send normal urgency warning notifications
- Update process_color to track clipboard failure and trigger error notification
- Improve warning message when clipboard utilities (wl-copy/xclip) are absent
The `--alpha` flag and `alpha = true/false` config file options remain
functional but references to them are removed as they are now superseded
by the output formats with alpha channels (rgba, hexa, hsla).
New users/configurations should use the relevant output formats. The
legacy flag/options remain active for backward-compatibility with older
configs/scripts.
This PR modernizes `color-tool` with a suite of new features, improved architecture, and automated release workflows.
### 🚀 Key Features
* **Multiple Format Support**: Now supports `hex`, `hexa`, `rgb`, `rgba`, `hsl`, and `hsla` output formats.
* **Flexible Output**: Use the new `--output` flag to specify one or more formats (e.g., `--output hex,hsl`).
* **Visual Swatches**: Added a `--swatch` flag to display a colored block in the terminal next to the values.
* **Intelligent Parsing**: Improved color input parsing that handles various CSS-style color strings.
* **Modern CLI Interface**: Added support for `--no-` flags (e.g., `--no-copy`, `--no-pick`) for fine-grained control.
* **Embedded Picker Support**: The KDE Plasma color picker logic is now more robustly managed and can be automatically generated if missing.
### 🛠 Architectural Improvements
* **Robust Configuration**: Refactored the config loader to support a clear priority hierarchy: **CLI Flags > Desktop Config > Default Config**.
* **Simplified Distribution**: Removed the hard dependency on an external `.py` file by embedding the picker helper script generation.
* **Installation Enhancements**: The `--install` process now handles `.desktop` file generation, symlinking, and sample configuration seeding more reliably.
### 📦 CI/CD & Documentation
* **Automated Releases**: Added a Gitea Action to automatically create a versioned release and upload the `color-tool` binary whenever a PR is merged into `main`.
* **Comprehensive Docs**: Added a new `README.md` with detailed installation, usage, and configuration guides.
* **Licensing**: The project is now explicitly licensed under **GPLv3** with appropriate headers and a `LICENSE` file.

Integration for the KDE Plasma color picker is based on the work by [SASUPERNOVA](https://github.com/SASUPERNOVA/wl-colorpicker-plasma).
Reviewed-on: #1
- Added --output flag supporting hex, rgb, hsl, rgba, hsla, hexa, and 'all' formats
- Implemented HSL/HSLA conversion using internal Python logic
- Added --[no-] prefix support for all toggleable flags (json, name, swatch, copy, notify, pick)
- Embedded KDE Plasma color picker Python script within the main bash script for portability
- Refactored argument parsing to implement a robust priority system (CLI > Desktop Config > Default Config)
- Improved validation to catch invalid output formats before triggering the color picker
- Updated installation logic to generate all necessary components and sample configuration
- Fixed swatch formatting when outputting JSON
- Refined desktop mode behavior and configurability
