Remove the 272 daily.dev "Explore top posts about ..." feed links
from 274 topic files across all roadmaps.
Three links were tagged @feed@ but are regular resources, so they
are retagged instead of removed:
- computer-science/sql-vs-nosql-databases: roadmap.sh guide -> @article@
- backend-beginner/git: YouTube crash course -> @video@
- game-developer/unreal-engine: Unreal Source Discord -> @article@

A repo-wide scan found 34 resource lines that link to an identical URL
as another line in the same file. Most look like content-sync artifacts
where a refreshed resource was appended but the stale one was never
removed; three were created by my earlier link fixes folding a dead URL
into an identical live one (cloudflare calls, cloudflare service
bindings, kotlinlang flow).
In each file the first occurrence is kept and only the later duplicate
is removed; no URLs or labels were modified.

Live replacements (5):
- concurrent-ruby: versioned docs URL 404s, updated to the unversioned
docs home
- IBM prompt injection article: research.ibm.com moved to
ibm.com/think/insights
- bolt.new: support-center quickstart removed, linked the official docs
- ML Basics book PDF (mlops): dead github.io copy replaced with the
live copy in the book's GitHub repository
- libretexts unbalanced tree: corrected the page slug (had a stray
trailing 'e')

cointelegraph crypto faucets, codewithmukesh NLog post, dhanusir ruby
