## Description

---

Provider/model selection, runtime and interaction mode changes, env mode and start-from-origin changes, and the model-disabled reason move into `chat/useComposerSelection.ts`, which selects its own draft-store setters. Verbatim move.

| | Before | After |
|---|---|---|
| `ChatView.tsx` lines | 4,415 | 4,271 |

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.
