**Title:** Add unit tests for prompt priority and link CRUD

**Status:** done

**Dependencies:** 40 ✓, 41 ✓

**Priority:** high

**Description:** Create comprehensive unit tests for all prompt CRUD operations with the new priority and linkTarget fields.

**Details:**

1. Add tests in `/src/mcpd/tests/services/prompt-service.test.ts`:
   ```typescript
   describe('Prompt Priority', () => {
     it('creates prompt with explicit priority', async () => {
       const prompt = await service.createPrompt({ ...data, priority: 8 });
       expect(prompt.priority).toBe(8);
     });
     
     it('uses default priority 5 when not specified', async () => {
       const prompt = await service.createPrompt(data);
       expect(prompt.priority).toBe(5);
     });
     
     it('validates priority range 1-10', async () => {
       await expect(service.createPrompt({ ...data, priority: 11 }))
         .rejects.toThrow();
     });
     
     it('updates priority', async () => {
       const updated = await service.updatePrompt(id, { priority: 3 });
       expect(updated.priority).toBe(3);
     });
   });
   
   describe('Prompt Links', () => {
     it('creates linked prompt', async () => {
       const prompt = await service.createPrompt({
         ...data,
         linkTarget: 'project/server:uri'
       });
       expect(prompt.linkTarget).toBe('project/server:uri');
     });
     
     it('rejects invalid link format', async () => {
       await expect(service.createPrompt({
         ...data,
         linkTarget: 'invalid'
       })).rejects.toThrow();
     });
     
     it('linkTarget is immutable on update', async () => {
       // linkTarget not accepted in update schema
     });
   });
   ```

**Test Strategy:**

This task IS the test implementation. Verify:
- All priority CRUD tests pass
- All link CRUD tests pass
- Validation tests cover edge cases
- Tests use proper mocking patterns
- Coverage meets project standards
