**Title:** Add linkStatus to prompt GET responses

**Status:** done

**Dependencies:** 56 ✓

**Priority:** medium

**Description:** Modify the GET /api/v1/prompts endpoint to include linkStatus (alive/dead/unknown) for linked prompts by checking link health.

**Details:**

1. Update `/src/mcpd/src/routes/prompts.ts` GET endpoint:
   ```typescript
   fastify.get('/api/v1/prompts', async (request, reply) => {
     const prompts = await promptService.findAll(filter);
     
     // Check link status for linked prompts
     const promptsWithStatus = await Promise.all(
       prompts.map(async (p) => {
         if (!p.linkTarget) {
           return { ...p, linkStatus: null };
         }
         const status = await linkResolver.checkLinkHealth(p.linkTarget);
         return { ...p, linkStatus: status };
       })
     );
     
     return reply.send(promptsWithStatus);
   });
   ```

2. Consider caching link health to avoid repeated checks

3. Add `linkStatus` field to prompt response schema:
   - `null` for non-linked prompts
   - `'alive'` for working links
   - `'dead'` for broken links
   - `'unknown'` for unchecked links

**Test Strategy:**

- Unit test: Non-linked prompt has linkStatus=null
- Unit test: Linked prompt with working link has linkStatus='alive'
- Unit test: Linked prompt with broken link has linkStatus='dead'
- Unit test: Link health cached to avoid repeated checks
- Unit test: All prompts in response have linkStatus field
- Integration test: End-to-end GET with linked prompts
