chore: adopt Vite+ (vp) for the JS toolchain (#417)

## Summary

Adopt Vite+ (`vp`) as this repo's JavaScript toolchain, so the project
behind `vp run` dogfoods Vite+ for its own formatting and git hooks.
This replaces the root `oxfmt` + `husky` + `lint-staged` setup with `vp`
and consolidates tool config into `vite.config.ts`.

## Changes

- **Formatting**: remove the root `oxfmt` dependency and
`.oxfmtrc.json`; format with `vp fmt` (config moved into the `fmt` block
of `vite.config.ts`). CI now runs `pnpm exec vp fmt --check`.
- **Git hooks**: replace `husky` + `lint-staged` with `vp config`
(`.vite-hooks/`) and a `staged` block that runs `vp check --fix` (plus
`cargo fmt` for Rust files).
- **Lint**: add a `lint` block with `ignorePatterns` for `playground/**`
and `**/fixtures/**`, so type-aware checks skip the nested playground
workspace and the intentionally-incomplete test fixtures.
- **Catalog**: route `vite`/`vitest` to the Vite+ forks
(`@voidzero-dev/vite-plus-core` / `-test`), pinned to `^0.1.23`.

## Notable decisions

- **`packages/tools` stays on standalone
`oxlint`/`oxfmt`/`oxlint-tsgolint`.** The `fspy` suite
(`crates/fspy/tests/oxlint.rs`) traces those real binaries' filesystem
access; the Vite+ `oxlint`/`oxfmt` bins are IDE/LSP wrappers and would
break the tests.
- **Root gains direct `vite`/`vitest` devDeps** so the catalog override
has a dependency to bind to. Otherwise the only `vite` reference is a
peer that pnpm satisfies with upstream vite, leaving the override a
no-op.

## Verification

`vp check`, `vp fmt --check`, and `pnpm dedupe --check` pass locally;
full CI is green (format, clippy, and all test shards including the
`fspy` oxlint tests).
