What's Changed

• Add native YYYY-MM date ranges. 2025-01 and [2025-01 TO 2025-01] now resolve to the full month of January, with support for range components, comparison operators, and inclusive/exclusive boundaries. Includes coverage for leap years, offsets, invalid input, and date limits. (#162)
• Correct standalone DateMath month bounds: DateMath.Parse("2025-01", baseTime, isUpperLimit: true) now returns the end of January 31 instead of January 1. Named timezones use the offset at the resolved boundary, including daylight-saving changes.
• Include the README in the NuGet package and expand date-range examples and regression coverage.
• Update build and test tooling, including the xUnit 4 migration.
