v2.7.0

• Provider metadata uses provider-specific terminology (instance, vm_size, zone, location, image, specs)
• Improved SSH config compatibility: UTF-8 BOM, Host= syntax, ${VAR} in includes, quoted paths, depth 16
• Automatic repair of absorbed group comments and orphaned group headers
• Synced hosts insert adjacent to existing provider group for consistent grouping
• Multi-level undo for host deletion (up to 50 levels)
• Welcome screen with one-time backup of original SSH config to ~/.purple/config.original
• Advisory file locking prevents concurrent write corruption
• New hosts insert before trailing Host * blocks to preserve SSH first-match-wins ordering
• Inline comments preserved when updating directives
• UpCloud boot disk preferred over first storage device for image metadata
• Scaleway pagination via response body instead of X-Total-Count header
• Proxmox QEMU OS type labels match qm.conf(5) manpage
• Atomic writes call fsync before rename and clean up temp files on failure
