v0.2.5

GitPilot v0.2.5 —Normalized Stability and UX polish. Unified brand palette across web, VS Code extension, and PyPI assets. Fixes the CrewAI planner "not enough values to unpack" error on malformed repo names, silences the spurious "Agent Error" flash on folder-only VS Code sessions, and repairs the UserMenu dropdown that was clipped when the sidebar is collapsed. Ships faster backend startup via lazy imports, a new zero-dependency /api/ping endpoint, session-list caching for WSL, and chat history hydration on session click. VS Code webview gets a cleaner Quick Actions section (unwired Project Overview chips removed), stale-file tsconfig fix, and Ollama / deepseek-r1 reasoning-model compatibility.
