The user wants to save something to CyxCode's project memory system.

Save the user's message as a memory file in .opencode/memory/.

1. Read the existing .opencode/memory/index.json (create if missing with {"version": 1, "entries": []})
2. Generate an id from the content (lowercase, hyphens, max 40 chars)
3. Extract tags: file names, technology keywords, significant words
4. Write the memory content to .opencode/memory/{id}.md (1-5 lines max, be concise)
5. Add an entry to index.json:

   {
     "id": "the-id",
     "file": "the-id.md",
     "tags": ["tag1", "tag2"],
     "summary": "one line summary",
     "created": "YYYY-MM-DD",
     "accessed": "YYYY-MM-DD",
     "accessCount": 0
   }

6. Confirm what was saved
