Refresh configs, add update.fish, rewrite README as setup runbook

- Re-dump brewfile (adds postgresql@16, tree; drops typeit4me)
- Refresh claude-settings.json, hosts, and serena_config.yml from machine
- Add update.fish to actualise the copied configs in one go
- Rewrite README as a complete ordered fresh-machine setup guide
