[Bug] Auto-memory writes inline content to MEMORY.md instead of creating linked files

Bug Description
Auto-memory writes inline content to MEMORY.md instead of creating linked files

The auto-memory system instructions explicitly state MEMORY.md should be an index only (links + brief descriptions), with content in separate .md files. In practice,
Claude sometimes writes memory content directly as inline sections into MEMORY.md — no separate file, no frontmatter, no link.

Impact: Skills that read individual memory files to extract frontmatter silently miss these entries. Inline content also consumes the 200-line index budget and
doesn't carry per-file staleness warnings.

Suggested fix: Add a hard rule and negative example to the system instructions: never write content directly into MEMORY.md. A lint check on MEMORY.md writes would
catch violations automatically.
