feat: generalize session sending with multiline text and structured mentions

Add named-session file/image/reply sending, preserve multiline text, and share safe member/all mention handling. Protect existing drafts, bind popup selection to the current window, validate structured mention tokens, and require fresh matching visible messages without automatic resend. Core tests: 121 passed. Windows 4.1.13.63 final validation: 9/9 passed. Record explicit coverage limits and sanitized evidence.
