Voltius v0.19.0

Added

• Voltius can now act as an MCP server, so Claude Code and other MCP clients
  drive your infrastructure directly: 41 tools covering keys, identities,
  connections, sessions, commands and file transfers. It is off by default —
  turn it on in Settings → Integrations, which also carries the one-line client
  setup command and what granting a client this access means.
• Plugins can contribute their own MCP tools. With the server on, the bundled
  Docker, Proxmox, process manager and monitoring plugins contribute 15 verbs
  between them — container and image listings, LXC actions, snapshots, process
  listing and metrics — and each plugin can be excluded on its own.
• An MCP client can read its own audit trail through audit_query, behind a new
  danger-gated audit:read permission.
• Plugins get a gated SFTP file domain and a gated api.mcp capability for
  contributing tools.

Fixed

• A Proxmox command that failed reported success. Creating, rolling back or
  deleting an LXC snapshot returned OK even when Proxmox refused the operation,
  so a rollback could target a snapshot that was never created.
• Creating a folder from the Snippets page put it in the Personal vault instead
  of the vault being viewed.
• Team-vault connections were adopted and rewritten by SSH config sync.
• Streaming a container's logs left a listener behind after the call finished.
• Russian was missing plural forms in the MCP integrations screen.
