Preserve user content in marker-less CLAUDE files during sync#353
Merged
Conversation
- Route a non-empty CLAUDE file without mcs markers through the update path so hand-written rules survive instead of being overwritten - Append managed sections below preserved content; only nil/whitespace files fresh-compose - Cover marker-less preservation, idempotency, and single-pack swap in unit + lifecycle tests

Summary
Syncing a tech pack into a pre-existing
CLAUDE.md(global) orCLAUDE.local.md(project) that held hand-written rules but no mcs markers overwrote the whole file, keeping only the pack sections. A timestamped backup was written, but the live file lost the user's content. Both scopes now preserve that content the same way an already-managed file does.Changes
