Add support for Gemini CLI hook-based integration, similar to Claude Code:
- bd setup gemini: Install SessionStart/PreCompress hooks
- bd setup gemini --check: Verify installation
- bd setup gemini --remove: Remove hooks
- bd setup gemini --project: Project-only installation
- bd setup gemini --stealth: Use bd prime --stealth
Also adds Gemini CLI integration check to bd doctor.
Gemini CLI's hook system is nearly identical to Claude Code's,
making this a clean, low-maintenance addition.
