fix: use basename instead of parse

To continue to have A+ support (specifically path.parse doesn't exist in [email protected])

style: lint fixes

fix: local content should use fs for inlining

The issue here was that although the "simple" detection was in place if the URL looked like HTML (i.e. has an angle bracket in it), but it didn't ever set the `isFile` flag.

This fix corrects this, but also swallows ENOENT errors, to mirror >=400 response codes being swallowed (i.e. return an empty body).

Fixes remy#89

chore: skip test dir in npm pkg

fix: move tap-only to devdeps

Fixes remy#92
