What changed

• Replace the Fire TV WebView catalog with a bundled empty RSS reader. It has no preloaded directory, show artwork, live search, or catalog requests.
• Fetch only an HTTPS feed after the user presses Load; limit feed size and episode count, follow only HTTPS redirects, and render feed text without HTML.
• Update the Appstore listing to describe the actual reader and its network behavior; replace the old directory screenshots with 1920x1080 emulator captures of the empty app and URL keyboard.
• Remove the stale live-directory screenshot capture script and obsolete offline page.
• Bump the signed app to version 1.1.0 (versionCode 2).

Verification

• docker run ... gradle:8.7-jdk17 sh build.sh — lint, compile, signed release APK, package/version metadata, and signer lineage passed.
• docker run --device /dev/kvm ... gradle:8.7-jdk17 bash emulator-test.sh — API 30 Android TV emulator passed; confirmed initial blank reader, native URL keyboard, explicit Load action, and HTTP URL rejection.
• git diff --check passed.

Amazon Developer Portal listing changes and resubmission require an authenticated seller session; this PR prepares the app and listing content but does not claim an Amazon submission.
