bug: expand_task MCP tool maps to 'expand-task' but actual CLI command is 'expand'

[reinamora137]

Description

The expand_task MCP tool's documentation and CLAUDE.md references suggest the CLI equivalent is task-master expand-task, but the actual CLI command is task-master expand. This causes failures when agents fall back to CLI for timeout-prone operations.

Steps to Reproduce

1. Try task-master expand-task --id 5 --tag "my-tag"
2. Command fails — expand-task is not a valid subcommand
3. Correct command: task-master expand --id 5 --tag "my-tag"

Expected Behavior

Either:

• The CLI should accept expand-task as an alias for expand, OR
• Documentation/CLAUDE.md should reference the correct command expand

Actual Behavior

The CLAUDE.md template (auto-generated by task-master init) contains multiple references to task-master expand-task which is not a valid command. The correct command is task-master expand.

Affected Documentation

In the generated CLAUDE.md, these lines reference the wrong command:

• "CLI: task-master expand-task --id X --tag Y"
• Multiple examples in the "Subtask Creation Guidelines" section

Environment

• Task Master version: 0.43.0
• Node.js version: v24.13.0
• Operating system: Ubuntu 24.04
• IDE: Claude Code CLI
