MAS-WP-0009 T01: independent JS implementation (impl/js), differential test, SCP-9

Browse source 
impl/js (Node, zero deps, written from the specs): parser, v0.2
statute-aware rules, signing, outside master. Passes addresses.json,
statute-aware.json and auth.json unchanged; its master passes the 11
slave-setup mode flows against the Python email side (ExternalMaster).
Differential testing vs mas_core found two unstated stand-in rules, now
SCP-9 in the v0.2 draft with fixtures si-011..013, dt-109; ABNF comments
no longer say v0.1. Runner: external masters, step errors fail the flow.
