v0.1.0

Initial public release of sss-ssh-keygen.

Highlights:

• opinionated wrapper around OpenSSH ssh-keygen for consistent, reviewable key-generation defaults
• software key default: ed25519
• hardware-backed default: ed25519-sk -O verify-required
• hardware compatibility fallback: ecdsa-sk -O verify-required
• RSA fallback profiles for compatibility and FIPS-oriented estates
• explicit dry-run, config-file, passphrase, and overwrite controls
• public-release documentation and repo hygiene files: README.md, LICENSE, SECURITY.md, and CONTRIBUTING.md
