Nothing else from Vite+ is used, and Oxlint reads the same rules from
.oxlintrc.json. This drops vite-plus and with it Vitest, a second copy
of Vite and about 130 packages.

Replace ESLint, typescript-eslint, eslint-plugin-node and the flat
config helpers with vite-plus, which runs Oxlint for vp lint. The rules
are carried over from eslint.config.mjs by @oxlint/migrate into the lint
section of the root vite.config.ts. The formatting rules ESLint
deprecated run as @stylistic rules through Oxlint's JS plugin support,
and disable comments naming them are updated to the @stylistic names.
@stylistic understands TypeScript syntax that the core rules skipped,
so the autofix adds missing semicolons and spaces in type literals and
aliases. Leading | and & in multiline types stay where they were.
Oxlint's node/no-sync also reports identifiers ending in Sync that are
not calls. The test helper techSync is renamed and the two other names
are ignored.
