fix: only warn about ignored flags when explicitly passed via CLI (#373)

The warning about launch-time options being ignored (when daemon is
already running) was incorrectly shown when options were set via
environment variables like AGENT_BROWSER_EXECUTABLE_PATH, even when
no CLI flag was passed.

Now the warning only appears when flags are explicitly passed on the
command line, not when values come solely from environment variables.

Fixes #372
