## Description

---

`CommandPalette.tsx` is ~3,400 lines: one 2,600-line dialog component builds every item, runs every add-project flow, and renders the results. Layer 2 of a stack that splits it into focused files so each piece reads on its own and the React Compiler caches each piece on its own inputs.

Moves thread items into `useCommandPaletteThreadItems` in `CommandPaletteThreadItems.tsx`. It owns the thread search, the provider entry map and the thread row content. The environment, project and sorted-group lookup hooks move to `CommandPaletteLookups.ts` so both files can share them.

This is the layer with the render win. In the dialog, the compiler cached the thread items in a scope that typing invalidated, so every keystroke rebuilt them and re-rendered the visible thread rows. In the hook, they depend only on the deferred search query. `ThreadCommandSubtitle`, `ThreadRowLeadingStatus`, `ThreadSearchPullRequestNumber` and `ThreadRowTrailingStatus` drop from 80 renders each to 0.

| | before | after |
|---|---|---|
| `CommandPalette.tsx` lines | 3249 | 3055 |
| Renders, open palette + type 10 chars (median of 3) | 2684 | 2352 |

Measured with the fiber render counter, same browser session and seeded dev DB, swapping only the palette files between this layer and the one below it. Behavior is unchanged.

Tests: `vp test run src/reactCompilerCoverage.test.ts -t CommandPalette` (0 bailouts, new files included), `vp test run src/components/CommandPalette.logic.test.ts`, `tsc --noEmit` for apps/web, `vp lint` on changed files.
