Add skill trees, achievements, statistics, and rebalanced progression

[Copilot]

Implements slower, more strategic progression with skill trees, achievements, and comprehensive statistics tracking. Addresses issue #30 requirement for skill trees and statistics.

Changes

Skill Tree System

• 3 skill paths (Click, Idle, Economy) with 9 upgradeable skills
• Prerequisite chains require sequential unlocking within paths
• Skill points earned via achievements and rebirths
• Multiplicative bonuses: +5-25% per level to click power, auto clickers, conversion rate, or crate discounts

Achievement System

• 13 achievements across clicks, cash, upgrades, and special categories
• Real-time progress tracking with visual bars
• Rewards: 1-10 skill points per achievement unlock

Statistics Tracking

• 9 lifetime stats: total clicks, cash earned, upgrades purchased, rebirths, play time, and peak values
• Persisted with game state, auto-updating during gameplay

Progression Rebalancing

• Expanded from 8 to 13 shop upgrades with intermediate tiers
• Increased base costs (15% average) and adjusted scaling for extended gameplay
• New upgrades: Enhanced Cursor, Helper Bot, Small Factory, Laboratory, Portal

UI

• Top bar adds Skills, Achievements, Stats buttons
• Skill Points display in header stats
• Three new modals with category-organized layouts

Technical Details

Skill modifiers apply multiplicatively:

const prestigeMultiplier = 1 + (prestigeCurrency * 0.01);
const skillMultiplier = 1 + skillModifiers.clickPowerBonus;
const effectiveClickPower = Math.floor(clickPower * prestigeMultiplier * skillMultiplier);

Achievement progress auto-updates via statistics tracking:

const checkAchievements = useCallback(() => {
  setAchievements(prevAchievements => {
    return prevAchievements.map(achievement => {
      let currentProgress = /* match stat to achievement type */;
      if (currentProgress >= achievement.maxProgress && !achievement.unlocked) {
        // Grant skill points and notify
      }
      return { ...achievement, progress: currentProgress };
    });
  });
}, [statistics]);
