Pull request overview

This pull request vendors the jupyter-dark-detect package into the codebase to simplify conda-forge packaging by eliminating an external dependency. The PR also updates copyright years from 2025 to 2026 across all source files and adds a custom wrapper module with a modified detection order optimized for EasyDiffraction's use case.

Key changes:

• Vendors jupyter-dark-detect package under src/easydiffraction/utils/_vendored/jupyter_dark_detect/
• Adds custom theme_detect wrapper module with detection order: JupyterLab settings → VS Code settings → JavaScript DOM → System preferences
• Updates import from jupyter_dark_detect to the vendored easydiffraction.utils._vendored.theme_detect in production code
• Removes jupyter_dark_detect dependency from pyproject.toml while keeping darkdetect for system-level detection
