Summary

Fixes a bug where year-less, slash-separated dates (e.g., 6/20(木)) failed to parse correctly when the lang: "ja" option was active.

Details

• Reorders the conditional checks in the addYearToDateText function to prioritize generic date formats over language-specific ones.
• The previous logic incorrectly formatted slash-separated dates as 2025年6/20(木), which broke the date parser.
• The new logic ensures slash (/) and dash (-) formats are handled first, guaranteeing correct year supplementation.

Behavior Before vs. After

With options { useCurrentYearIfMissing: true, currentYear: 2025, lang: "ja" }:

Before

• Input: "6/20(木)"
• Result: Fails to detect weekday mismatch.

After

• Input: "6/20(木)"
• Result: 6/20(木) mismatch weekday.\n6/20(木) => 6/20(金)

Background

This patch addresses an edge case not covered in the initial implementation of the useCurrentYearIfMissing option (see #14), improving the rule's reliability for common date formats in Japanese.
