Move all inlined news entries from news.nix into separate files
organized
by year and month. This makes the news system more maintainable and
easier to navigate.
- Extract 202 inlined entries to individual files in YYYY/MM directory
structure
- Update news.nix to only contain the module definition
- Use recursive directory traversal to find all news entries
- Update news.nix to recursively search for news entries in
subdirectories
- Update create-news-entry.sh to place new entries in YYYY/MM/
directories
- Move existing 2025 news entries to the new structure
This makes the news directory more organized and easier to navigate.
The current way to define a news entry in Home-Manager is error prone
(since you need to type the date manually) and also it is common cause
of conflicts after merges because all entries are defined in the same
file.
This commit fixes this: we can now create individual news entries for
each new entry. A script `create-news-entry.sh` also helps to create it
in the correct format (with the correct filenames and structure).
