Moves the React client from Vite 7 + ESLint + tsc to Vite+, VoidZero's unified toolchain:

	Before	After
Dev / build	Vite 7, tsc -b && vite build	vp dev / vp build (Vite 8, Rolldown)
Type check	tsc -b	vp check (Oxlint type-aware, TypeScript Go)
Lint	ESLint 9 + 7 plugin packages (config failed to load on main)	vp lint (Oxlint)
Format	none	vp fmt (Oxfmt)
Tests	none	vp test (Vitest 5), 5 seed tests

All tool config (lint, fmt, test) is in one vite.config.ts. The npm scripts are still the entry points, so the .NET integration (npm run build in the publish target, RunNodeProcess, the .esproj) is unchanged, and no global vp install is needed.

Commits

1. Format MyApp.Client with Oxfmt: formatting only, listed in .git-blame-ignore-revs.
2. Migrate MyApp.Client to the Vite+ toolchain:
   • vite-plus 1.4.0 with npm overrides
   • lint rules ported from the ESLint config
   • ESLint, the duplicate PostCSS config and postinstall.mjs removed (empty DBs are already migrated on app startup)
   • seed tests added
   • deps upgraded to latest, including TypeScript 7
   • package-lock.json committed
3. Update CI and docs for Vite+, add VS Code workspace:
   • new client job in build.yml; setup-vp replaces setup-node in build-container.yml
   • AGENTS.md and README updated, including that dtos.ts is regenerated on .NET startup
   • MyApp.code-workspace added

Worth reviewing

• Hook rule findings. The ESLint config never loaded, so these had never been reported. lib/auth.tsx got small fixes that don't change behaviour: the HOC's inner component is renamed to PascalCase, and shouldRedirect is now declared before the useEffect that uses it. appAuth() is a hook without a use prefix and is shared by 7 templates, so it keeps its name and the rule is suppressed per line. A rename across all templates is a separate change.
• Lint warnings. Two rules that ESLint never ran (no-floating-promises, react/purity) are set to warnings. vp check passes with 12 warnings.
• Bundle size is 584 kB, up from 513 kB. This isn't caused by Vite+: a fresh install of main's Vite 7 setup also produces 583 kB, because newer dependency versions resolve when there's no lockfile.
• VS Code. Open MyApp.code-workspace rather than the folder. The Oxc extension only resolves vite-plus from a workspace root's node_modules.

Verified locally

• npm ci, then npm run check, npm run test:run and npm run build all pass. Builds take about 190 ms, down from about 915 ms.
• Type errors are still caught: a planted TS2322 fails vp check.
• Running through .NET at https://localhost:5001:
  • the Vite client and React Refresh are served through the proxy
  • /api/Hello responds
  • the HMR websocket upgrades (101)
• dotnet publish runs vp build and copies the output to wwwroot.
• With an empty database, the app bootstraps the schema and seed data on startup, without postinstall.mjs.
• Not done: clicking through the UI in a browser, and running the CI workflows on GitHub (this PR is their first run).
