Problem

A mobile game team at NovaPlay wants a simple Tic-Tac-Toe engine that supports gameplay, tracks the running score, and allows resetting either the board or the full match. Implement the core game logic.

Write a function that processes a sequence of commands for a 3x3 Tic-Tac-Toe game. Players alternate as X then O. Valid move commands place the current player's mark on the board. When a player wins, that player's score increases by 1 and the board automatically resets for the next round, starting again with X. A draw also resets the board with no score change. Invalid moves are ignored.

Formal Specification

Input: commands, a list of commands where each command is one of:

{"type": "move", "row": int, "col": int}
{"type": "reset_board"}
{"type": "reset_all"}

Output: a dictionary with:

board: final 3x3 board as a list of lists containing "X", "O", or ""
current_player: "X" or "O"
score: { "X": int, "O": int }

Constraints

1 <= len(commands) <= 10^4
Each command is a dictionary with a type field
For move commands, row and col are intended to be integers in the range [0, 2]
Invalid moves do not change the board, score, or current player
After any win or draw, the board resets and the next round starts with player X
