Document a Sphinx extension surface

Render one config value:

```{eval-rst}
.. autoconfigvalue:: sphinx_fonts.sphinx_font_preload
```

Render every config value from an extension module:

```{eval-rst}
.. autoconfigvalues:: sphinx_config_demo
```

Exclude specific config values (useful when two extensions register the same value and Sphinx warns on the duplicate confval):

```{eval-rst}
.. autoconfigvalues:: sphinx_gp_llms
   :exclude: site_url
```

Builders and domains follow the same single/bulk pattern:

```{eval-rst}
.. autobuilder:: my_project.builders.ZipBuilder
```

```{eval-rst}
.. autodomains:: my_project
```

Bulk forms accept either an extension package (its setup() is replayed so add_builder() and add_domain() registrations surface) or a plain module (scanned for Builder / Domain subclasses).
