Feature request: lightweight 👍/👎 acknowledgment on assistant messages (not just model feedback)

Problem Statement

As a heavy daily Claude Code user (web/iPhone sessions), many assistant messages are status updates or FYI info that don't need a typed reply — but I often want to acknowledge them: "got it," "heck yes," "good job." Right now the only way is typing a message, which costs a full turn and interrupts work in progress.

Request: a small thumbs-up / thumbs-down (or emoji react) affordance on each assistant message — ideally per-message, even better per-paragraph — that (a) lets the user acknowledge without composing a message, and (b) is visible to the model as lightweight feedback ("user acknowledged / approved this") so it knows the message landed without needing a reply.

This is different from the existing model-quality feedback thumbs: it's conversational acknowledgment, like message reactions in iMessage/Slack. It would reduce round-trips and make long working sessions (builds, deploys, monitoring) feel much more natural.

Proposed Solution

Request: a small thumbs-up / thumbs-down (or emoji react) affordance on each assistant message — ideally per-message, even better per-paragraph — that (a) lets the user acknowledge without composing a message, and (b) is visible to the model as lightweight feedback ("user acknowledged / approved this") so it knows the message landed without needing a reply.
