Document the three-tier identity model across MCIAS, MCR, Metacrypt,
MCNS, and MCP. Update version numbers for MCR (v1.2.1), MCNS (v1.1.1),
MCP (v0.7.2). Clarify that admin is reserved for MCIAS administration,
not routine deploy operations.

Metacrypt SSH CA, transit, and user-to-user engines are all implemented
(not planned). MCR is at phase 13. MCDSL package list was incomplete.
