Add app version to TizenTube Settings entry (build: enable JSON imports)

[KrX3D]

Summary

This PR improves the Settings UX by showing the current app version directly in the TizenTube Settings entry.

The previous subtitle text (“Open TizenTube Settings”) was a bit redundant, because the page title/button already communicates that selecting it opens the settings page. Replacing it with the version makes the entry more useful for debugging and support.

Picture

Changes

• UI: mods/ui/customYTSettings.js

  • Replaces the old subtitle text with Version: <package.json version> (e.g. Version: 1.12.7)
  • Reads the version from package.json

• Build: mods/rollup.config.js

  • Adds @rollup/plugin-json so Rollup can import package.json

• Dependencies: mods/package.json

  • Adds @rollup/plugin-json (and lockfile updated accordingly)

Notes

• No runtime behavior change besides the settings entry subtitle; this is a small UX/support improvement.
