Rule parser now accepts iptables-style:
ACCEPT input -p tcp --ctstate ESTABLISHED,RELATED
DROP forward state NEW
Both 'state' and '--ctstate' keywords work. States are case-
insensitive: NEW/New/new, ESTABLISHED/Established/established,
RELATED/Related/related, INVALID/Invalid/invalid.
Comma-separated lists (e.g. 'ESTABLISHED,RELATED') use the FIRST
recognized state only — FilterRule stores a single StateMatch field.
Docstring updated with new examples.
All 31 tests pass.
