feat(EchoTypes): register v0.2.0 (#20)

EchoTypes v0.2.0 landed at hyperpolymath/EchoTypes.jl#4 (admin-merged
2026-05-27 due to Actions budget exhaustion; locally 167/167 tests
pass on Julia 1.10.11 + 1.12.6).

Adds 7 executable mirrors of the Tier-1+Tier-2 spine from echo-types
@ e7dded6 (EchoTotalCompletion, EchoOrthogonalFactorizationSystem
unconditional fragment, EchoImageFactorization, EchoNoSectionGeneric,
EchoLossTaxonomy, EchoEntropy, EchoObservationalEquivalence).
R-2026-05-18 retraction discipline preserved; funext-qualified
clauses honestly NOT mirrored.

Tag v0.2.0 at tree-sha1 70839093d66f216d338bfaa4e0e6098435fc7858.
Compat unchanged (julia 1.10, no new runtime deps).
