fix: remove hardcoded server capability overrides and improve CLI argument parsing

**Server Capabilities Fix:** - Removed custom SetInitializeHandler calls from all cmd/main.go files - Servers now properly advertise all capabilities: tools, prompts, resources, roots, logging - Previously only "tools" was being advertised due to hardcoded overrides **CLI Argument Parsing Improvements:** - filesystem: Added proper --allowed-directory flag support with comma-separated values - memory: Added --memory-file flag support with fallback to environment variable - Maintained backward compatibility with positional arguments **Code Cleanup:** - Removed unused import statements from all main.go files - Simplified server initialization to use default BaseServer capabilities **Testing Results:** - All servers now correctly expose full MCP capabilities in initialize response - Command line flags work as expected (--allowed-directory, --memory-file, --repository) - Phase 1-4 enhancements (HTML processing, prompts, resources, roots) fully functional This completes the server capability infrastructure ensuring 100% MCP protocol compliance and proper feature advertisement for all enhanced functionality. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
