Subject: [PATCH 2/2] Add isRenderedTextFile and hasRenderedText functions

Implements detection for rendered text files including markdown, textile, rdoc, org, creole, mediawiki, wiki, rst, asciidoc, and pod files. The hasRenderedText function combines isRepoRoot with isRenderedTextFile to identify pages that display rendered text content.
