[Feature Request] Add granular session sharing controls with selective opt-in and sharing preferences

When Claude Code asked "Can Anthropic look at your session transcript to help us improve Claude Code?", I wanted to say yes — but the current all-or-nothing framing stopped me. Two issues:

[a] Incentives: Sharing session data has real value for Anthropic. A discount, credits, or token allocation in return would make opting in a much easier decision.
[b] Granular consent: I don't want to share everything. I'd like to opt in at a finer level — e.g., per-session, per-machine, or only when I explicitly flag a conversation. Specific use case: when I hit a frustrating or broken experience, I want to be able to say "look at this specific session" and have someone at Anthropic actually review it. A "flag this session for review" button would be very useful.
