⚡ Summary of Changes

This PR introduces three major upgrades to Kernel:

1. 🎨 Dynamic Cyberpunk Theme Engine (/theme [name])

• Adds ThemePalette registry supporting 6 distinct terminal aesthetics:
  • cyberpunk (Default neon cyan/violet)
  • matrix (Phosphor green mainframe)
  • dracula (Gothic vampire purple & pastel)
  • nord (Arctic blue & icy aurora)
  • tokyo (Tokyo night storm & lavender)
  • synthwave (Sunset magenta & neon grid)
• Dynamic Lip Gloss style recalculation at runtime via ApplyTheme().
• Persists theme selection to ~/.kernel/config.json.

2. ⚡ AI Conventional Commit Assistant (/commit [-y])

• Inspects git status and git diff across the active workspace.
• Generates professional Conventional Commit messages (feat(...), fix(...), refactor(...)).
• Supports /commit for preview and /commit -y to auto-stage and commit in one step.
• Offline heuristic fallback ensures instantaneous responses even in demo mode.

3. 🐶 Authentic Canine & Feline Audio Engine

• Replaced synthetic SAPI speech imitation with authentic embedded .wav animal recordings.
• Uses native Windows WinMM API (winmm.dll -> PlaySoundW) with SND_MEMORY | SND_ASYNC for zero-latency, in-memory playback.
• Added cross-platform audio fallbacks for macOS (afplay) and Linux (aplay).

🧪 Verification

• All test suites passing (go test ./... -> 100% green).
• Clean compilation verified on Windows amd64.
