**Title:** Update Prompt CRUD API to handle priority and linkTarget

**Status:** done

**Dependencies:** 37 ✓

**Priority:** high

**Description:** Modify prompt API endpoints to accept, validate, and return the priority and linkTarget fields. LinkTarget should be immutable after creation.

**Details:**

1. Update `/src/mcpd/src/validation/prompt.schema.ts`:
   ```typescript
   export const CreatePromptSchema = z.object({
     name: z.string().min(1).max(100).regex(/^[a-z0-9-]+$/),
     content: z.string().min(1).max(50000),
     projectId: z.string().optional(),
     priority: z.number().int().min(1).max(10).default(5).optional(),
     linkTarget: z.string().regex(/^[a-z0-9-]+\/[a-z0-9-]+:[\S]+$/).optional(),
   });
   
   export const UpdatePromptSchema = z.object({
     content: z.string().min(1).max(50000).optional(),
     priority: z.number().int().min(1).max(10).optional(),
     // Note: linkTarget is NOT included - links are immutable
   });
   ```

2. Update `/src/mcpd/src/routes/prompts.ts`:
   - POST /api/v1/prompts: Accept priority, linkTarget
   - PUT /api/v1/prompts/:id: Accept priority only (not linkTarget)
   - GET endpoints: Return priority, linkTarget in response

3. Update repository layer to handle new fields

4. Add linkTarget format validation: `project/server:resource-uri`

**Test Strategy:**

- Unit test: POST /api/v1/prompts with priority creates prompt with correct priority
- Unit test: POST /api/v1/prompts with linkTarget creates linked prompt
- Unit test: PUT /api/v1/prompts/:id with priority updates priority
- Unit test: PUT /api/v1/prompts/:id rejects linkTarget (immutable)
- Unit test: GET /api/v1/prompts returns priority and linkTarget fields
- Unit test: Invalid linkTarget format rejected (validation error)
- Unit test: Priority outside 1-10 range rejected
