This change renames all occurrences of "contrast" to "saturated" to better describe the functionality:
- Config option `foreground` now accepts "saturated" instead of "contrast"
- All internal color palette variables renamed from *Contrast to *Saturated
- Documentation updated to reflect the new terminology
Migration guide:
- If using `foreground = "contrast"`, change to `foreground = "saturated"`
- If using `foreground = { dark = "contrast", light = "contrast" }`, change to `foreground = { dark = "saturated", light = "saturated" }`
Adds an EditorConfig file to maintain consistent coding styles across editors. Reformats code with consistent indentation using spaces instead of tabs. Makes minor color palette adjustments.
