Owner playtesting found that hammering a gem (or line-bombing a gem line)
removed it visually but did not satisfy the clear-gems objective and never
completed the stage — it felt broken. Per owner decision, booster clears
now count: a hammered gem emits gems:1, a line-bomb emits lines:1 + the
line's gem count, both folded through the objectives. After any booster the
engine resolves the phase (completed objective -> won, else re-check stuck),
which was the direct cause of the stage not finishing. Score and the move
counter remain untouched. Reverses the earlier no-objective-credit rule.
