Fixes a remaining issue reported by @akok where internal and external links were flagged as broken due to a trailing quote being appended during URL extraction.
Bug Fix
Link checker trailing quote - the plain URL regex was re-matching inside already-parsed [URL='...'] BBCode blocks, capturing the closing quote as part of the URL. This caused valid links to be reported as broken with ' appended. The fix strips all [URL] blocks before running the plain URL regex, making duplicate extraction impossible.
