Subject: [PATCH] fix: avoid crash when jekyll-archives.layouts is not a hash

Handle malformed jekyll-archives.layouts config defensively by
falling back to the default layout key instead of calling dig on
a non-Hash value.

Add regression coverage for malformed layouts config to ensure
archive generation does not crash.

Fixes #181
