## Description

---

Reverting to an earlier turn, rolling back a provider checkpoint, and forking from a run move into `chat/useTimelineRewind.ts`, with the commands only they use. Verbatim move.

| | Before | After |
|---|---|---|
| `ChatView.tsx` lines | 4,881 | 4,715 |

Tests: `tsc-rs --noEmit` for apps/web, oxlint on the changed files, `vp test run src/components/ChatView.logic.test.ts`, and the React Compiler coverage test for every changed file (0 bailouts). ChatView stays in the coverage test's slow set.

Part of the ChatView split (7,258 → 3,975 lines across the stack).

Opus 5.5, Claude Code.
