MCP task status lines are cleaned before display

MCP task status lines are cleaned of control characters before printing, so a server can't mangle your terminal.

What

The status row for a running MCP task now passes the server name, tool name and status message through a sanitizing step before printing, and shortens the task id with a helper instead of a fixed eight-character cut. This hardens the line against control characters or overlong names sent by an MCP server. Exactly what the sanitizer strips is not settled by the code shown.

Evidence

mcp_task

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
