/**
 * Structural tests for `gbrain dream` argv parsing (v0.21).
 *
 * Verifies the help text + parser source contains the new flags
 * (--input, --date, --from, --to) and that conflict detection is wired.
 * The actual parseArgs is internal; we exercise it via the source file
 * structure to avoid spinning up a process per test.
