fix: bridge host global Claude memory into container

[dlovell]

Summary

• Container Claude sessions never received the host's top-level ~/.claude/memory (cross-project feedback and preferences) — only per-project memory was bridged.
• setup-claude.py copied the host CLAUDE.md but not the sibling memory/ dir. This adds copy_global_memory(), mirroring the existing copy pattern.

Notes

• One-time copy at init, consistent with how the script bridges everything else (CLAUDE.md, prefs). Host memories written after init won't sync until the next init.
• Global feedback memories are portable preferences, so copying is low-risk; the only thing to watch is a memory that hardcodes a host path.

Test plan

• Re-run dev/devcontainer init and confirm ~/.claude/memory/ in the container contains the host's global memory files (e.g. feedback_code_style.md).
• Confirm per-project memory still bridges correctly.
