fix(mcp): include r.memory in getProfile fallback chain

[muhammedhunaid]

Summary

• Add missing r.memory fallback in getProfile() searchResults mapping
• Aligns with existing search() method behavior (line 140)
• Fixes empty memory content in MCP recall tool output

Related discussion: #694

Problem

The recall tool returns match percentages but empty memory content:

### Memory 1 (73% match)

### Memory 2 (72% match)

Root Cause

getProfile() at line 175 was missing r.memory in its fallback chain:

// Before
memory: limitByChars(r.content || r.context || ""),

// After  
memory: limitByChars(r.content || r.memory || r.context || ""),

Test plan

• Verify recall returns memory content with the fix
• Confirm search behavior unchanged

Pull request overview

This PR fixes a bug in the MCP recall tool where memory content was not being displayed. The getProfile() method was missing r.memory in its fallback chain when mapping search results, causing empty memory content to be returned even when the memory field contained data.

Changes:

• Added r.memory to the fallback chain in getProfile() method to align with the existing search() method behavior
