feat: complete redesign to v2.4.0 - Claude's ultimate development partner

Major redesign of Gemini MCP Server with modular architecture:

- Removed all emoji characters from tool outputs for clean terminal display
- Kept review category emojis (🔴🟠🟡🟢) per user preference
- Added 4 specialized tools:
  - think_deeper: Extended reasoning and problem-solving (temp 0.7)
  - review_code: Professional code review with severity levels (temp 0.2)
  - debug_issue: Root cause analysis and debugging (temp 0.2)
  - analyze: General-purpose file analysis (temp 0.2)
- Modular architecture with base tool class and Pydantic models
- Verbose tool descriptions with natural language triggers
- Updated README with comprehensive examples and real-world use cases
- All 25 tests passing, type checking clean, critical linting clean

BREAKING CHANGE: Removed analyze_code tool in favor of specialized tools
