MAS v0.2 final (MAS-WP-0009 finished); residual MAS-WP-0014

Founder decision after the second implementation: close the two open gaps,
then declare v0.2 final. Section 13: parsers MUST reject over 64 octets
(fixtures p1-050/051); section 8: equivalence is between targets, key format
not normative. Draft markers removed, CHANGELOG dated 2026-10-19,
MAS_VERSION 0.2, mas_conformance vendors the v0.2 addresses.json. Mode
contract v0.1 stays draft: MAS-WP-0014 (independent email side).
