eat(models): Add MCP support for models command and improve configuration docs

This commit implements several related improvements to the models command and configuration system:

- Added MCP support for the models command:
  - Created new direct function implementation in models.js
  - Registered modelsDirect in task-master-core.js for proper export
  - Added models tool registration in tools/index.js
  - Ensured project name replacement when copying .taskmasterconfig in init.js

- Improved .taskmasterconfig copying during project initialization:
  - Added copyTemplateFile() call in createProjectStructure()
  - Ensured project name is properly replaced in the config

- Restructured tool registration in logical workflow groups:
  - Organized registration into 6 functional categories
  - Improved command ordering to follow typical workflow
  - Added clear group comments for maintainability

- Enhanced documentation in cursor rules:
  - Updated dev_workflow.mdc with clearer config management instructions
  - Added comprehensive models command reference to taskmaster.mdc
  - Clarified CLI vs MCP usage patterns and options
  - Added warning against manual .taskmasterconfig editing
