test: Add comprehensive automated tests for Bot private message processing
- Created new LocalNetAppChat.Bot.Tests project - Added unit tests for private message command processing - Added end-to-end scenario tests simulating the complete message flow - Tests verify that commands like "exec calculate.ps1" work without "/" prefix - Added tests for both private and public message handling - Includes test coverage for various command formats and edge cases All 71 tests pass successfully (8 new Bot tests + 63 existing). 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
