perf(trampoline): raw Win32 rewrite shrinks vp-shim to 14KB

[fengmk2]

This PR is an alternative to #2465. It keeps build-std and replaces std::process::Command with raw Win32 API calls.

The canonical CI build produced these x64 results:

Artifact	Base	This PR	Change
vp-shim.exe	214.00 KiB	14.00 KiB	-200.00 KiB (-93.46%)
gzip -9	103.20 KiB	7.09 KiB	-96.11 KiB (-93.13%)

On Windows, the executable imports only KERNEL32. It uses #![no_main], mainCRTStartup, and an atexit stub to exclude CRT startup code.

• The shim reads the adjacent <name>.shim file. It supports versioned single-root and split layouts.
• It normalizes drive-letter and UNC paths before Win32 API calls. This permits paths longer than 260 characters.
• It passes the original UTF-16 argument tail to CreateProcessW. It keeps quotation marks unchanged.
• It inherits redirected standard handles. The child handles console control events. The shim returns the child exit code.
• It reports the failed operation, the related path, and the GetLastError code. A missing vp.exe message gives repair instructions.

Non-Windows builds use the portable implementation. Unit tests cover sidecar parsing, path handling, and command-line parsing.

Registry bridge build (2d4a47d)

This commit build is published to the registry bridge, which serves these as ordinary npm versions (every other package proxies to npmjs):

Package	Version
vite-plus	0.0.0-commit.2d4a47d7bba13bdbc0206399e87e506cd39eab36
@voidzero-dev/vite-plus-core	0.0.0-commit.2d4a47d7bba13bdbc0206399e87e506cd39eab36

Install the Vite+ CLI built from this commit, then migrate a project:

# macOS / Linux
curl -fsSL https://raw.githubusercontent.com/voidzero-dev/vite-plus/2d4a47d7bba13bdbc0206399e87e506cd39eab36/packages/cli/install.sh | VP_PR_VERSION=2466 bash

# Windows (PowerShell)
$env:VP_PR_VERSION="2466"; irm https://raw.githubusercontent.com/voidzero-dev/vite-plus/2d4a47d7bba13bdbc0206399e87e506cd39eab36/packages/cli/install.ps1 | iex

Or download the standalone Windows installer built from this commit:

Architecture	Installer
x64	vp-setup-x86_64-pc-windows-msvc.exe
Arm64	vp-setup-aarch64-pc-windows-msvc.exe

GitHub requires you to sign in and downloads each installer as a ZIP artifact. Extract vp-setup.exe, then run it against this preview build:

.\vp-setup.exe --version "0.0.0-commit.2d4a47d7bba13bdbc0206399e87e506cd39eab36" --registry "https://registry-bridge.viteplus.dev/"

After installing, upgrade the current project's vite-plus to this test build with:

vp migrate

Or point your package manager at the bridge registry https://registry-bridge.viteplus.dev/:

Package manager	Registry config
npm / pnpm / Bun	.npmrc: registry=https://registry-bridge.viteplus.dev/
Yarn (v2+)	.yarnrc.yml: npmRegistryServer: "https://registry-bridge.viteplus.dev/"

Then pin the build (vite aliases to vite-plus-core; pnpm can use a catalog, npm an overrides entry):

{
  "devDependencies": {
    "vite-plus": "0.0.0-commit.2d4a47d7bba13bdbc0206399e87e506cd39eab36",
    "vite": "npm:@voidzero-dev/vite-plus-core@0.0.0-commit.2d4a47d7bba13bdbc0206399e87e506cd39eab36"
  }
}
