Extension not detected on GNOME Shell 47-49

[danielbanariba]

Description

The extension cannot be enabled on GNOME Shell 47, 48, or 49. Running gnome-extensions enable brainusage@altairinglorious returns:

Extension "brainusage@altairinglorious" does not exist

The extension files are correctly installed in ~/.local/share/gnome-shell/extensions/brainusage@altairinglorious/, but GNOME Shell refuses to recognize it.

Root Cause

metadata.json only declares shell-version: ["45", "46"]. GNOME Shell silently ignores extensions that don't include the running Shell version in their compatibility list.

Environment

• GNOME Shell 49.5
• Wayland session
• CachyOS (Arch-based), kernel 6.19.10

Expected Behavior

The extension should be recognized and loadable on GNOME Shell 47, 48, and 49.

Suggested Fix

Add versions "47", "48", and "49" to the shell-version array in extension/metadata.json.
