feat: rename Built-in source type to Stdlib and show it in downloads column

Standard-library entries rendered "Not on PyPI" in the PyPI Downloads
column, which read like missing data rather than a deliberate category
— the build already forces downloads to None for them so they never
pick up a same-named PyPI backport. They now render a "Stdlib" badge
instead, while genuine non-PyPI entries keep "Not on PyPI".

The filter tag is renamed to match, so the source-type value, the row
filter tag, and the synthetic category heading all read Stdlib now.
The literal "Built-in" strings scattered through build.py are routed
through the existing BUILTIN_FILTER constant so the label lives in one
place. The category page slug stays "built-in" so the public URL
/categories/built-in/ does not break.
