root ed0aff4714 feat(data): expand challenge seed list from 5 to 25 seeds
Adds 4 more rounds of 5 seeds each, organized by difficulty tier.
Seeds wrap modulo list length so the pool grows non-destructively.

//! Static seed list for Challenge mode + helpers.
//!
//! Challenge mode walks a fixed sequence of hard-but-winnable seeds. The
//! player advances by winning a deal in `GameMode::Challenge`. The
//! `challenge_index` cursor is stored per-player in `PlayerProgress`.
//!
//! Seeds wrap modulo `CHALLENGE_SEEDS.len()` so a sufficiently dedicated
//! player never runs out of challenges.
/// Curated Challenge-mode seeds. Order is stable across versions; add new
/// seeds at the end.
