research: VIV driver — exact seed window, error status, no overwrite, bounded smoke flag

Browse Source 
Seed quiet check reads states y_t, t in [n_seed - 5 T_n, n_seed); an
exception sets status 'error: ...' before the report is written; an output
directory that already holds report.json or steps.npy is refused; --max-steps
gives a plumbing smoke that is never scored. Predeclare states the code's
actual uniform-U fluid initial condition.
