feat: complete MCP TypeScript implementation with tests

- Add comprehensive test suites for ACI and MCP packages
- Fix ACI TypeScript build errors (Region type conflicts, Key enum conversion)
- Rename palette system to mode presets throughout codebase
- Add all 100 historic programmer modes from Python dev tool
- Add 13 mode presets from Python MCP (unix, modern, web, scripting, etc.)
- Fix circular dependency in MCP by creating tool-registry.ts
- All tests passing: AI (31), ACI (29), MCP (33)
