PR Summary

This PR adds a new Doorstopper extension that prevents MacBooks from sleeping when the lid is closed, with commands to enable/disable the functionality and monitor status through both command palette and menu bar.

• The CHANGELOG.md entry title needs to use {PR_MERGE_DATE} instead of hardcoded date "2025-03-19"
• The startDoorstopper/stopDoorstopper functions in src/util.ts should be wrapped in try-catch blocks since they use execSync with sudo privileges
• The launchCommand calls in src/util.ts could be simplified using showFailureToast from @raycast/utils for error handling
• The menu bar command should have a subtitle set to "Doorstopper" in package.json to match the extension title
• The media/capture-1.png screenshot appears to be duplicated in both media/ and metadata/ folders, should be consolidated

@pernielsentikaer LGTM.

The media/capture-1.png is redundant. We could remove it later since the ray publish has a bug on removing files.
