Memory writes should have distinct visual styling in terminal output

When Claude saves a memory (writing to the memory system), the tool call output looks the same as any other file write — grey text that blends into the noise. It's easy to miss that a memory was created or updated.

Suggestion: Give memory operations (writes to the memory directory) a distinct color, icon, or formatting in the terminal so they stand out. Something like a brief highlighted line: [Memory saved: feedback_improve_as_we_go.md]

This would help users stay aware of what's being persisted across conversations without having to scan every tool call.

We verified this isn't configurable via settings or hooks — it's a genuine feature gap.
