ToolAhead 0.5.0

Antigravity lifecycle hooks: init-antigravity now installs .agents/hooks.json with a fail-open adapter for Antigravity's native tool events. Learning, service pre-warming, and route warming work even when the agent uses only native tools — the ToolAhead MCP tools remain necessary only for replay hits. The adapter always answers a neutral {} with exit 0, so it can never block the agent's tool calls.
