src/github/utils.ts:1668

• The new getStateFromQuery function lacks test coverage. Given that the codebase has tests for other utility functions in src/test/github/utils.test.ts (e.g., getPRFetchQuery and sanitizeIssueTitle), tests should be added for this new function. Consider adding test cases for:

• Queries with is:open, is:closed, and is:merged
• Queries without a state qualifier
• Queries with state qualifiers in different positions (start, middle, end)
• Case insensitivity (IS:OPEN, Is:Closed, etc.)
• Queries with multiple state qualifiers (should match the first one)
• Edge cases like "is:opened" or "is:merge" (should return undefined)

export function getStateFromQuery(query: string): GithubItemStateEnum | undefined {
	const match = query.match(/(?:^|\s)is:(?<state>open|closed|merged)(?:\s|$)/i);
	if (!match?.groups?.state) {
		return undefined;
	}
	switch (match.groups.state.toLowerCase()) {
		case 'open':
			return GithubItemStateEnum.Open;
		case 'closed':
			return GithubItemStateEnum.Closed;
		case 'merged':
			return GithubItemStateEnum.Merged;
		default:
			return undefined;
	}
