Replace the writable+derived store pipeline in state.ts with a
state.svelte.ts module: a deep $state inputState mutated only through
the exported update functions, each of which persists the snapshot and
re-validates it asynchronously into validatedState.current (with
urls.current derived from it). Store subscriptions in components become
$effect blocks, and the rough/grid toggles use function bindings.

Adding the `svelte-check` CI gate surfaced pre-existing type errors and
warnings under develop's TypeScript 6 / Svelte 5.56 bump. Fixes them so
`pnpm check` reports 0 errors / 0 warnings:
- Add `lang="ts"` to Share/Privacy (and a script to PrivacyPolicyLink) so
importers get real declarations instead of implicit `any`.
- Replace the deprecated `monaco.languages.json` with the new top-level
`monaco.json` namespace (proper API, no casts).
- Navbar: use `resolve('/', {})` instead of the deprecated `base`.
- Type the promo `component` as `Component<{ closeBanner: Snippet }>` and
MainMenu's `renderer` as `Snippet<[Omit<MenuItem, 'renderer'>]>`.
- Index-by-string casts in state.ts / Preset / DiagramDocumentationButton.
- Make Actions' clipboard handler accept an optional event.
- toggle-group: expose variant/size via getters to fix the
state_referenced_locally warning.
- Make the History e2e save/delete cases change state via a sample
diagram (deterministic) instead of editor typing.

Bump the full dependency tree (Vite 8, Vitest 4, ESLint 10, Svelte 5.56,
mode-watcher 1.x, etc.) and adapt code for breaking API changes. Upgrade
Playwright CI image to v1.60 for Node 24 compatibility.
