Add tags and categories to posts, and create a default tag page

[mrbiggred]

Enabled the tag plugin and used AI to add tags and categories to all posts. Also reordered the menu items.

@normanlorrain and @o-ashour let me know what you think. I haven't had a chance to check if the tags make sense. I'll likely check them later this week.

Looks good! Just wondering if some brief documentation about adding/removing tags and/or categories would be useful here. Is there particular formatting / casing? Even a link to the mkdocs page for them might be sufficient.

[normanlorrain]

I like it. Btw, looking at the tag list showed that
docs/posts/2025/09/09/index.md
is missing a title in the Yaml.

[o-ashour]

Looks reasonable to me.

[mrbiggred]

@normanlorrain I added the title to 2025/09/09. @o-ashour I've added some documentation to the README. Let me know if the documentation is not clear.

[mrbiggred]

Merging the PR. If anyone spots any issues, let me know or feel free to fix them yourself.

[o-ashour]

Nice job on the readme!
