chore: expand and clean up .claude/settings.json

- broaden the permission allowlist (git porcelain, file utils, curl)
- "preferences" key (tmux split panes, markdown responses)
- tighten the deny list (force-push, git clean, destructive rm)
- keep only permissions relevant to this repo (generic `bash scripts/*`
  covers its own scripts; no jetson/agent-swarm template entries)
