• feat: Confident edits on every host, shared lines included.
• feat: Multi-alias Host lines like Host web-01 web-01.prod are first-class in the TUI. Edit, rename and delete them from any alias and the on-disk config keeps up.
• feat: Deleting one alias from a shared line keeps the surviving aliases and their shared directives in place, ready to use.
• feat: The delete confirm dialog spells out the sibling aliases that will survive, so you press y knowing exactly what stays.
• change: Vault SSH certificates and Vault HTTP endpoints scope themselves per-alias automatically, keeping shared lines clean.
• change: OpenSSH itself is now a test oracle. Purple's parse and serialize cycle is cross-validated against ssh -G on 16 curated configs plus every fuzz seed, on top of 637k-run fuzzing.
