Pressing Esc in the project MCP approval prompt now aborts startup and returns to the terminal instead of treating Esc as **Deny** and continuing into the TUI. --- Esc now produces the same launch-cancellation outcome in both project MCP selectors. The explicit **Deny** option remains available and selected by default, so declining trust still requires choosing it and pressing Enter.

Pressing Esc in the project MCP approval prompt now aborts startup and returns to the terminal instead of treating Esc as Deny and continuing into the TUI.
Esc now produces the same launch-cancellation outcome in both project MCP selectors. The explicit Deny option remains available and selected by default, so declining trust still requires choosing it and pressing Enter.
