Fix incomplete mock data in issueTodoProvider test

[Copilot]

This PR fixes an inconsistency in the mock document data within the issueTodoProvider.test.ts file.

Issue

Line 37 had an incomplete mock function string 'function test() {' (missing the closing brace), while other similar test cases on lines 86 and 122 correctly used 'function test() {}'.

Changes

Updated the mock document on line 37 to use the complete function signature:

// Before
lineAt: (line: number) => ({ text: line === 1 ? '  // TODO: Fix this' : 'function test() {' })

// After  
lineAt: (line: number) => ({ text: line === 1 ? '  // TODO: Fix this' : 'function test() {}' })

This ensures consistency across all test cases in the file and properly represents a complete JavaScript/TypeScript function in the mock data.

Verification

• ✅ ESLint passes
• ✅ TypeScript compilation succeeds
• ✅ Hygiene checks pass
