fix(cli): inline lint-staged version into staged debug bundle

[rokuosan]

Problem

• vp staged --debug crashes by reading vite-plus/dist/package.json instead of lint-staged's package.json #1922

vp staged --debug crashes in the published package.

When debug logging is enabled, bundled lint-staged calls getVersion()(lib/version.js), which reads its own manifest viareadFile(new URL('../package.json', import.meta.url)). The CLI bundleslint-staged into dist/staged/bin.js, so that relative ../package.json does not exist at runtime and the command throws instead of printing the debug log.

This is exactly what the pinned lint-staged@16.4.0 does in lib/version.js:

import fs from 'node:fs/promises'

export const getVersion = async () => {
  const packageJson = JSON.parse(await fs.readFile(new URL('../package.json', import.meta.url)))
  return packageJson.version
}

Source: https://github.com/lint-staged/lint-staged/blob/445f9dd042b88528c798b2e25c21c9adbc69a732/lib/version.js#L1-L6

Fix

Add a tsdown plugin (inline-lint-staged-version) that rewrites the
./version.js import coming from lint-staged/lib/index.js to a virtual module
exposing the dependency version resolved at build time:

export const getVersion = async () => "16.4.0";

Keeps the getVersion named-export shape identical, so no lint-staged internals change.

Tests

• Extend the command-staged-with-config global snap test with a vp staged --debug step that must succeed. A regression flips the recorded exit code (> → [1]>), failing the snapshot.

Verified against a real build: dist/staged/bin.js now contains the inlined const version = "16.4.0" and no longer references readFile(new URL('../package.json', ...)).

Thanks, that matches the direction I had in mind.

One small alternative: how about replacing lint-staged/lib/version.js directly?

It could make the change a bit shorter, since the debug path calls getVersion() here:
https://github.com/lint-staged/lint-staged/blob/5f3b8f28e895972bd5a2cdba733327b49859b91f/lib/index.js#L106-L115

and getVersion() is isolated in lib/version.js:
https://github.com/lint-staged/lint-staged/blob/5f3b8f28e895972bd5a2cdba733327b49859b91f/lib/version.js#L3-L6

Not blocking though — the current approach also looks clear to me.

Also, could you please look into the CI failure?

Thanks, that makes sense.
Replacing /lint-staged/lib/version.js directly is simpler here, so I'll update it.

I'll also investigate the CI failure.
