tiennm99 35578d00fe feat(card): avoid 3 consecutive filled columns in any row ...

Soft visual constraint: no row has cols n, n+1, n+2 all filled.
Implementation = constraint-aware per-row picker (uniformly samples
triple-free completions of the forced+candidate set) + whole-grid
rejection sampling (up to 200 attempts). Hard invariants (5 per row,
5 per col, ascending column values) are never sacrificed; if the soft
constraint can't be met, the generator returns the best attempt.

- src/lib/game-logic.js: hasThreeInARow, combinations,
  pickFilledColsOnce, pickFilledCols rejection wrapper
- src/lib/game-logic.test.js: 300-trial strict assertion
- docs/codebase-summary.md, project-overview-pdr.md: note the rule
