feat(mcp): major MCP server improvements and documentation overhaul

- Enhance MCP server robustness and usability:
  - Implement smart project root detection with hierarchical fallbacks
  - Make projectRoot parameter optional across all MCP tools
  - Add comprehensive PROJECT_MARKERS for reliable project detection
  - Improve error messages and logging for better debugging
  - Split monolithic core into focused direct-function files

- Implement full suite of MCP commands:
  - Add task management: update-task, update-subtask, generate
  - Add task organization: expand-task, expand-all, clear-subtasks
  - Add dependency handling: add/remove/validate/fix dependencies
  - Add analysis tools: analyze-complexity, complexity-report
  - Rename commands for better API consistency (list-tasks → get-tasks)

- Enhance documentation and developer experience:
  - Create and bundle new taskmaster.mdc as comprehensive reference
  - Document all tools with natural language patterns and examples
  - Clarify project root auto-detection in documentation
  - Standardize naming conventions across MCP components
  - Add cross-references between related tools and commands

- Improve UI and progress tracking:
  - Add color-coded progress bars with status breakdown
  - Implement cancelled/deferred task status handling
  - Enhance status visualization and counting
  - Optimize display for various terminal sizes

This major update significantly improves the robustness and usability
of the MCP server while providing comprehensive documentation for both
users and developers. The changes make Task Master more intuitive to
use programmatically while maintaining full CLI functionality.
