docs(user): koreader install delegated to KOReader's own documentation

Owner ruling: we support the plugin, not the software. The per-device
install walkthroughs (Kindle launcher paths, Kobo .adds layout,
PocketBook package steps) were prose-trusted third-party knowledge —
exactly the kind of content this project can't verify and shouldn't
half-cover, especially since real installs usually involve jailbreaks
and extra launchers. Replaced with an honest scope note (we can't tell
you how to modify your device) plus a link to the KOReader project's
official installation guide, verified live: github.com/koreader/
koreader#installation routes to per-model wiki pages (Android, Kindle,
Kobo, PocketBook, reMarkable, and more). The plugin sections (git-clone
install, server URL, registration, the full menu tree) are unchanged —
that's our side and stays pinned to plugin source.

Also fixed while grounding: the Mobileread forum link pointed at f=271
but KOReader's own README badges f=276 as their subforum; and the
resources section now carries their user-guide link (koreader.rocks/
user_guide) alongside installation.

 ## Installing KOReader
 
-### Kindle Devices
+One honest note first: **Bookhoard supports the Bookhoard sync plugin —
+not KOReader itself.** Getting KOReader onto an e-reader usually involves
+device-specific steps (jailbreaks, alternative launchers, one-click
+packages) that vary by model and firmware. That's the KOReader project's
+domain, not ours — we can't tell you how to modify your particular device,
+and we won't pretend otherwise with half-remembered instructions.

+routes you to model-specific steps for Android, Kindle, Kobo, PocketBook,
+reMarkable, and more:
