fix(oxlint): support Vite+ via vp lint

[UfukUstali]

Vite+ exposes vp but no longer provides a standalone oxlint binary. The oxlint config already recognizes Vite+ projects, but it only looks for oxlint, so the language server fails to start when a project uses Vite+ without a separate oxlint installation.

Look for oxlint and vp in the project's node_modules/.bin before checking PATH. Keep oxlint preferred within each location, and start vp with lint --lsp when selected.

Related discussion: voidzero-dev/vite-plus#3016. That PR proposed restoring the editor binaries; the discussion explains that the wrappers were removed because they could conflict with the upstream packages during installation.

Validation: 48 executable-discovery cases in headless Neovim using temporary executable files, StyLua, LuaLS diagnostics, and the repository lint script all pass.

Vite+ exposes vp but no longer provides a standalone oxlint binary

This all sounds like gibberish to me. Is oxlint a separate project or is oxlint deprecated entirely?

If oxlint is a separate project, and "vite" was shipping oxlint as some sort of convenience, then it sounds like this change should be in a vite-specific config?

[UfukUstali]

oxlint is the actual linter. vite+ embeds oxlint and some other tools to provide complete js/ts ecosystem tooling. when using vite+ you don't need to seperatly install oxlint as it is already embeded and exposed as the vp lint command. the problem is oxlint is then not in the node_modules/.bin and only vp is. so this pr makes lspconfig look for vp as well as oxlint.

glancing at https://github.com/voidzero-dev/vite-plus , it looks like "vite plus" some sort of distro for "vite", and has nothing to do with vite itself.

This PR starts by casually mentioning "Vite+" as if that is just an obvious thing. Without explaining that Vite+ is a third-party wrapper around Vite.

So "vite plus" is doing random things and now expects the entire ecosystem (such as these lsp configs) to bend over for it?

[UfukUstali]

both oxlint and vite plus is developed by the same team. they just provide the option to use the linter however you see fit or as a part of a more complete toolset being vite+.

I see... well, good luck out there.
