Add the following news item to both News.md and history.md:

$ARGUMENTS

Follow these steps:

1. Parse the news content from $ARGUMENTS
2. Determine the appropriate month and year (ask if unclear)
3. Read both News.md and history.md files
4. Add the news item to history.md in the correct chronological position:
- Years are organized with `## Year` headings (e.g., `## 2026`, `## 2025`)
- Years are sorted descending (newest first)
- Create year section if it doesn't exist
- Months within a year are in chronological order (January at top)

The reason will be displayed to describe this comment to others. Learn more.

The documentation states "Months within a year are in chronological order (January at top)" but this is incorrect. Looking at the actual News.md and history.md files, months within a year are in REVERSE chronological order (newest first), with December appearing before November, November before September, etc. This inconsistency could lead to incorrect news item placement when following this documentation.

Suggested change
- Months within a year are in chronological order (January at top)
- Months within a year are in reverse chronological order (newest first, e.g., December before November)

Copilot uses AI. Check for mistakes.
- Format: `- [news content]`
5. Add the same item to News.md:
- Years are organized with `## Year` headings
- Find or create the correct year section
- Find or create the month subsection (### Month)
- Insert after the month heading
- The Durham announcement is a special item under the `## 2025` heading
6. Count regular news items in News.md (items that start with "- ")
7. If more than 5 regular news items exist, remove the oldest ones
- Special announcements (like Durham) don't count toward the 5-item limit
- Only remove items from the oldest months, preserving year structure
8. Ensure proper spacing between sections
9. Save both files

Important formatting:

- Year headings: `## 2026`, `## 2025`, etc.
- Month headings: `### January`, `### December`, etc.
- News items start with "- "
- Leave blank lines between different sections
- Special announcements (like Durham) use `### <i class="fa-solid...">` format
- Special announcements don't count toward the 5-item limit

Structure example:

```markdown
## 2026

### January

- [News item]

## 2025

### <Special announcement with icon>

[Announcement content]

### December

- [News item]
```
