v5.4.0

• Added task and project subtask date rollup operations, with task mismatch status and job progress.
• Added creation-time filtering, comment filtering, and sort direction for task and goal stories.
• Added html_custom_fields input for rich text in text custom fields, plus custom_type and custom_type_status_option task inputs.
• Clarified portfolio visibility and nested opt_fields documentation.
• Corrected the Roles and project status schemas to match existing server validation: Roles listing requires workspace, role creation rejects super_admin, and project status creation requires color. These are spec corrections, not new server restrictions.
