feat: replace lucide-solid icons with kilo-ui Icon component (Phase 1.5)

- All 15 lucide-solid icons in Settings.tsx replaced with Icon component
- Back button ArrowLeft → Icon name='arrow-left'
- Removed lucide-solid dependency from package.json
- Many icons use approximate matches (kilo-ui only has 38 icons)
- Update progress tracker + deviation note #7

 - See [`docs/ui-implementation-plan.md`](docs/ui-implementation-plan.md) for the full migration plan and phased rollout
 - **Check the desktop app first**: [`packages/app/src/`](../../packages/app/src/) is the reference implementation for how kilo-ui components are composed together. Always check how the app uses a component before implementing it in the webview — don't just look at the component API in isolation.
 - **`data-component` and `data-slot` attributes carry CSS styling** — kilo-ui uses `[data-component]` and `[data-slot]` attribute selectors, not class names. When the app uses e.g. `data-component="permission-prompt"` and `data-slot="permission-actions"`, these get kilo-ui styling for free.
+- **Icons**: kilo-ui has 75+ custom SVG icons in [`packages/ui/src/components/icon.tsx`](../../packages/ui/src/components/icon.tsx). To list all available icon names: `node -e "const c=require('fs').readFileSync('../../packages/ui/src/components/icon.tsx','utf8');[...c.matchAll(/^\\s{2}[\"']?([\\w-]+)[\"']?:\\s*\x60/gm)].map(m=>m[1]).sort().forEach(n=>console.log(n))"`. Icon names use both hyphenated (`arrow-left`) and bare-word (`brain`, `console`, `providers`) keys.

 4. **`Spinner` has no `size` prop**: The plan assumed `Spinner` would accept a `size` prop. The actual component is sized via CSS `style` prop (`width`/`height`).
 5. **Settings tab sidebar buttons**: Left as native `<button>` elements because they have complex active/hover state styling that would need significant rework to use `Button`.
 6. **Permission dialog vs inline prompt**: The desktop app renders permissions inline in the prompt dock area (replacing the input). The vscode webview keeps a `Dialog` wrapper because the layout differs. The inner content uses the same `BasicTool` + `data-component="permission-prompt"` pattern as the app. The args are shown as raw JSON rather than `perm.patterns` because the vscode permission data shape differs from the app's SDK format.
+7. **Icon mapping uses approximate matches**: kilo-ui only has 38 icons. The plan's mapping assumed icons like `providers`, `console`, `branch`, `server`, `help` exist — they don't. Current mapping uses best-available alternatives (e.g. `cloud-upload` for Providers, `chevron-right` for Terminal). These should be replaced with proper icons once they're added to the UI library.
