Voltius v0.23.0

Added

• The MCP server can now send real keystrokes. send_keys types into any open
  session — literal text or named keys like Enter, Up, Escape, C-c,
  F1–F12 — and returns the screen once it stops changing, so an agent can
  drive a full-screen program (top, less, fzf, vim, whiptail) that run_command
  structurally cannot: that verb wraps its input so it can read an exit code,
  and the wrapper is typed into such a program as literal text.
• Ten further verbs join it, taking the MCP surface from 48 to 59. Snippets can
  be run on a host, known hosts listed, trusted and deleted, and shell history
  searched across hosts. Transfers can be listed, cancelled and retried;
  configuration sync state and host reachability can be read.
• Transfers started over MCP now appear in your own transfer queue, marked with
  the name of the client that started them, and can be cancelled from there like
  any other transfer.
• Tabs a connected MCP client is driving are marked in the tab strip and the
  pane header, with the controlling client named in the tooltip, so it is always
  visible which sessions are not being driven by you.
• A failed transfer can be retried from the transfer queue.

Fixed

• A local shell could come up blank, and starting the app a second time opened a
  second copy instead of focusing the running one.
• Opening a new split tab cloned the previous tab's terminals into it.
• A session opened by an MCP client no longer steals the tab you are working in.
• An SFTP handle evicted from the cache was dropped without being closed,
  leaking it on the server.
• A transfer being retried could be evicted from the queue mid-retry.
• Editing a port-forwarding rule or a snippet over MCP no longer needs the whole
  record restated, and a transfer that failed to start reports the real error
  instead of silently resolving.
