Implementation

• Update write_summary title handling to rename the current meeting note for non-empty title values.
• Keep existing title behavior when the title parameter is omitted or blank.
• Update summary-agent instructions and tool description for generated default titles.
• Add focused tests for rename, omitted title, blank title, and instructions.
• Validate with focused tests, dotnet test MeetingAssistant.slnx, and openspec validate allow-summary-title-rename --strict.
