Add docs/THREAT_MODEL.md deriving a publishable threat model from
NATIVE_V1_SPEC.md sections 4-6: assets, in/out-of-scope attackers,
security properties vs SSH (including where Dosh aims to exceed it),
cryptographic building blocks as implemented, and an honest
accepted-residual-risks / known-gaps section.
Refresh docs/PUBLIC_READINESS.md: feature matrix now reflects native
auth, host-key trust, authorized_keys policy, doctor, and -L/-R/-D
forwarding; add a per-item "Native v1 verification checklist status"
table mapping spec section 16 to done/in-progress/pending from code.
Update README.md status with a native v1 section and honest claim
posture pointing to THREAT_MODEL.md. Annotate NATIVE_V1_SPEC.md with a
v1 status block summarizing milestone progress. Point SPEC.md security
model and header at native auth and the threat model.
