Add statusline scripts, context-load improvements, and prior distill updates

- Add statusline.sh and set-topic.sh for per-session status line topics
- Update context-load with improved directory walking and output format
- Update CLAUDE.md with status line docs and early-call safety note
- Update MEMORY.md and README.md with new script/skill entries
- Add memory files: script-statusline, skill-decompose, skill-orchestrate, gotchas-gitea
- Add networking.md best practice (nftables, systemd sockets, Docker forwarding, TLS)
- Update best practices from prior distill: documentation, kubernetes, scripting,
  secrets-management, skills-development
- Prune reflected session logs, add new session logs
- Update reflection state
