PR Summary

This PR adds a retry mechanism to handle missing Slack scopes by clearing tokens and re-authenticating when needed in the status setting functionality.

• The global retried flag in /extensions/slack/src/tools/set-status.ts could cause race conditions if multiple status updates happen simultaneously - consider making it request-scoped
• The error handling in /extensions/slack/src/tools/set-status.ts could be simplified using showFailureToast from @raycast/utils instead of throwing errors
• The launchCommand in /extensions/slack/src/tools/set-status.ts should be wrapped in a try-catch block for better error handling

logic: Global retried flag could cause issues if multiple status updates are attempted in the same session. Consider moving this into the function scope.

Suggested change

	let retried = false;
	async function setStatus(input: Input) {
	let retried = false;

Looks good and hopefully resolves the issue. I wonder if we should move that logic down into the utils. So other extensions would benefit of it as well.

res.error?.includes("missing_scope") is pretty specific to the Slack API - each API returns different stuff so hard to generalize
