Phase 6 part 2 (partial):
- daily_seed_for(date) and PlayerProgress::record_daily_completion in
solitaire_data, with streak logic that increments on consecutive days,
resets on a skipped day, and is idempotent on same-day re-completions.
- DailyChallengePlugin tracks today's seed, awards +100 XP and updates
the streak when the player wins a game whose seed matches. Pressing C
starts a new game with the daily seed.
- LevelUpEvent toast in AnimationPlugin announces level changes.
- AchievementContext gains daily_challenge_streak; daily_devotee
achievement unlocks at streak >= 7. AchievementPlugin reads
ProgressResource and runs after ProgressUpdate.

Introduces AchievementContext (stats + last-win snapshot), AchievementDef,
ALL_ACHIEVEMENTS, and check_achievements. Adds undo_count to GameState
so the no_undo and speed_and_skill conditions are evaluable.
Skipped achievements that depend on features not yet built:
daily_devotee (progress), comeback (recycle counter), zen_winner (modes),
perfectionist (max-score calc). They land in later phases.
