[FEATURE] Add option to disable memory feature or show CLAUDE.md edits as inline diffs

Preflight Checklist

Problem Statement

When Claude edits CLAUDE.md, changes are hidden behind "Wrote 1 memory (ctrl+o to expand)" instead of showing inline diffs.

I cannot review what Claude wrote before changes are applied. Claude may write incorrect information based on misunderstandings, and I have no way to disable this feature.

I maintain CLAUDE.md as version-controlled SSoT and need to see every edit like any other file.

Proposed Solution

Add setting to disable memory feature or show inline diffs:

{
"memory": {
"enabled": false,
"showInlineDiffs": true
}
}

Alternative Solutions

Currently I run git diff CLAUDE.md after each change to see what was written. This breaks workflow.

CLI commands and flags

Use Case Example

1. I maintain project documentation in CLAUDE.md (SSoT)
2. Claude suggests adding something to memory
3. I see only "Wrote 1 memory" - no diff shown
4. Change is already applied without my review
5. Later I discover Claude wrote something incorrect
6. I have to manually fix CLAUDE.md and commit

Additional Context

This was introduced in recent versions (~2.1.x). Previously edits to CLAUDE.md showed inline diffs like other files.
