modified: The matrix share feature is now only available when the `matrix-nio` dependency is installed.
If `matrix-nio` is not installed:
1. Apply a strikethrough to the matrix checkbox text in the share UI and display a tooltip.
2. A warning is logged at startup indicating that `matrix-nio` is missing, along with the installation command.
fixed: Corrected an issue where PR #2025 was merged into draft-v4 but applied only to `legacy/..` and not to `glob/..`
