♟ TakeTakeTake support

• Added support for taketaketake.com — the third site Chessolve works on.
• Added best-move suggestions and evaluation for games played there.
• Added support for both live bot games and daily puzzles.
• Adapted to a board that is drawn rather than built from page elements.
• Followed the site’s real game state instead of guessing from the board.
• Kept suggestions correct across rematches, new games, and game changes.
• Correctly identified who is playing which color, including bot games with no player name.

• Added analysis for taketaketake.com daily puzzles.
• Made puzzle analysis a Premium feature, with an upgrade button right on the best-move card.
• Added a Puzzle solved state to the best-move card.
• Applied a dedicated puzzle setup: fixed analysis depth, a single line, no auto-play, and no move-by-move review.
• Locked the corresponding analysis settings while solving a puzzle so they cannot be changed accidentally.
• Prevented an in-progress analysis result from appearing on a puzzle that has already been solved.
• Ensured the position only advances when the site itself confirms the move was accepted, and stays put otherwise.
