fix: add -NoProfile flag to PowerShell subprocess invocation

On Windows, PowerShell loads the user profile by default, which may
contain UI-related commands (e.g., setting CursorPosition) that fail
in a non-interactive subprocess environment. This causes all shell
commands to timeout with 'The handle is invalid' errors.

Add -NoProfile flag to skip profile loading in the shell tool's
PowerShell subprocess calls.

Fixes #1341
