Morse v0.18.1

MCP config edits arrive on their own, and a background session no longer strands a dialog.

New

• MCP changes appear without reopening anything. Adding, removing or toggling a server — in another window, or
  with the pi CLI in a terminal — updates the MCP indicator and panel as soon as the mcp.json file changes on
  disk, for both your user-level file and the project's.

Fixed

• A dialog from an extension in a background session is no longer lost. An interaction raised while you were
  looking at another tab used to be dropped, leaving that pi process waiting forever. Morse now tracks dialogs per
  session, answers the process that asked, shows one at a time (switching tabs swaps it), and marks a waiting
  session in the sidebar.
• The MCP indicator follows the session. Switching conversations re-probes that project's servers instead of
  leaving the previous project's dot, and coming back to the window re-reads it too.
• Deleting a session that is already gone no longer errors. When its file had been removed out of band, Delete
  failed after closing the agent; it is now idempotent.

Improved

• Long interaction dialogs. Multi-line titles wrap, a tall dialog scrolls, and an empty answer can be submitted.
