feat(cli): Add --status/-s filter flag to show command and get-task MCP tool

Implements the ability to filter subtasks displayed by the `task-master show <id>` command using the `--status` (or `-s`) flag. This is also available in the MCP context.

- Modified `commands.js` to add the `--status` option to the `show` command definition.

- Updated `utils.js` (`findTaskById`) to handle the filtering logic and return original subtask counts/arrays when filtering.

- Updated `ui.js` (`displayTaskById`) to use the filtered subtasks for the table, display a summary line when filtering, and use the original subtask list for the progress bar calculation.

- Updated MCP `get_task` tool and `showTaskDirect` function to accept and pass the `status` parameter.

- Added changeset entry.
