Fixes microsoft#15587. When the user has pre-existing text in the Aspire terminal input buffer, stop/restart/start commands get appended to it, making the resulting command invalid. Send a line-clearing control sequence (Ctrl+U on Unix, Escape on Windows) before each command to discard any buffered input.

Description
When the Aspire terminal has pre-existing text in its input buffer (e.g., a partially typed command), clicking Stop, Restart, or Start on a code lens or tree view appends the Aspire CLI command to the existing text, producing an invalid command that fails.
This fix sends a line-clearing control sequence before each command:
Ctrl+U(\x15) — clears the current input lineEscape(\x1b) — clears the current input lineFixes #15587
