Replace beforeEach hook with docsify's routes config that intercepts
.pine URL patterns before docsify attempts to fetch them as .md files.
The route handler fetches the actual .pine file and wraps it in a
markdown code fence, giving each .pine file a unique URL hash.
Replace manual click-interception plugin with a clean beforeEach hook
that detects .pine routes and wraps raw content in markdown code fences.
This gives each .pine file its own unique URL (e.g. #/lib/.../atr.pine),
supports direct linking, bookmarks, and browser back/forward navigation.
