When tool output contains ANSI colour codes and gets truncated (e.g. tsc error output with red background), the terminal retains the stale background colour until another log line happens to set a different colour.
Fix: Emit \x1b[0m (full ANSI reset) at the start of each logLine() call in Terminal, clearing any residual fg/bg colour from prior output before writing the timestamp.
