aider: Update title display based on page type.

# Aider chat conversation:

USER: in page.html, I want it to show "Freenet: Page Title" if it's on a page but just "Freenet" if it's the homepage

ASSISTANT: To achieve the desired behavior, we need to update the `page.html` template to conditionally set the title based on whether it's the homepage or another page.

Here are the *SEARCH/REPLACE* blocks:

templates/page.html
```python
<<<<<<< SEARCH
{% block title %}{{ page.title }}{% endblock %}
=======
{% block title %}
  {% if page.title == "Home" %}
    Freenet
  {% else %}
    Freenet: {{ page.title }}
  {% endif %}
{% endblock %}
>>>>>>> REPLACE
```

This change ensures that the title will be "Freenet" on the homepage and "Freenet: Page Title" on other pages.
