• status (optional): Initial status name

linear_search_issues

Search Linear issues with flexible filtering:

• query (optional): Text to search in title/description
• teamId (optional): Filter by team
• status (optional): Filter by status
• assigneeId (optional): Filter by assignee
• priority (optional): Priority level (0-4)
• limit (optional, default: 10): Max results to return
