* fix(antigravity): surface aborted Gemini tool calls off end_turn Gemini/Antigravity aborts a turn with finishReason MALFORMED_FUNCTION_CALL (or a sibling like UNEXPECTED_TOOL_CALL) instead of completing cleanly. Both Claude-facing translators collapsed these to a clean end_turn, hiding the aborted tool call as a successful completion: - the OpenAI hub path (openai-to-claude.ts convertFinishReason default), and - the DIRECT Gemini->Claude path (gemini-to-claude.ts), which is the one Claude Code actually hits through an antigravity/Gemini-routed model. Add isAbortFinishReason() to finishReason.ts and map these reasons to tool_use on both paths; genuinely unknown reasons still fall back to end_turn.
