- Create direct function wrapper in show-task.js with error handling and caching

- Add MCP tool integration for displaying detailed task information

- Update task-master-core.js to expose showTaskDirect function

- Update changeset to document the new command

- Follow kebab-case/camelCase/snake_case naming conventions
