Add grid re-sampling after game start detection

If initial calibration finds no grid (renderer: unknown), re-calibrate
after the game starts. Games that create DOM cells dynamically via JS
(innerHTML on render loop) have 0 children at page load but 200 after
starting. Records grid_detected_at: "initial" vs "after_start" in report.

Known issue: e2e04e75 game has startBtn button but bot falsely detects
start via Space (something changed but game didn't actually start).
Needs stronger start verification in next session.
