Improve git status indicators with conflict detection

[theantichris]

🎯 Objective

Enhance git status display with merge conflicts, stash detection, and better visual indicators.

🎨 Current State

[main●●●⇡2]  # Basic dots for all status types

✨ Enhanced State

[main▲●?⇡2]  # Distinct symbols for each status
[main▲●✗]    # With conflict indicator
[main▲●📦]   # With stash indicator

📋 Implementation

• File: dot_oh-my-zsh/custom/themes/cyberwave.zsh-theme
• Function: Enhance cyberwave_git_status()
• New Indicators:
  • ▲ Modified files (instead of first ●)
  • ● Staged files (keep current)
  • ? Untracked files (instead of third ●)
  • ✗ Merge conflicts
  • 📦 Stash present
  • Repository states (rebasing, merging, etc.)

🔧 Detection Methods

# Conflicts
git ls-files --unmerged | grep -q .

# Stash
git stash list | grep -q .

# Repository state
git status --porcelain -b | head -1

✅ Acceptance Criteria

• Clear visual distinction between status types
• Conflict detection works reliably
• Performance doesn't degrade in large repos
• Stash detection works
• Repository state detection (rebase, merge, etc.)
