Initial commit: dial — interactive SSH host picker

A fast, read-only ~/.ssh/config picker that exec's the system ssh client.
Includes: static high-contrast picker with recency/frequency/name sort and
tag grouping, `dial keygen` (native ed25519/RSA + optional config entry), and
an optional offline YubiKey launch gate with one-time recovery codes.
