fix: ipset compat with v7.x (plain text, timeout support, arg split)

Browse Source 
- list() now parses plain text (works on ipset 6/7/8, not just 8)
- Strip " timeout N" suffix from member lines (kernel adds it when set has timeout support)
- ensure_exists() creates set with 'timeout 0' so add() can use --timeout later
- Fix ensure_ipset_match_rule: split rule string into separate argv tokens
  (Command::args with whitespace string was treated as one arg, breaking nf_tables)
- Add #[serial] to tests sharing TEST_SET (race condition fix)
- Add 3 new tests: list_parses_plain_format_correctly, list_empty_set_returns_empty_vec,
  list_filters_non_ip_lines
- Simplify integration_netns.sh to use iptables-only assertions (ipset is host-global)
