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

[rokuosan]

Describe the bug

vp staged succeeds, but adding --debug causes Vite+ to crash while trying to read vite-plus/dist/package.json.

Expected:

• vp staged --debug should succeed and print the bundled lint-staged version correctly

Actual:

• vp staged --debug throws ENOENT for vite-plus/dist/package.json

Example with --debug:

$ vp staged --debug
node:internal/fs/promises:640
  return new FileHandle(await PromisePrototypeThen(
                        ^

Error: ENOENT: no such file or directory, open '/Users/rokuosan/.local/share/mise/installs/viteplus/0.2.1/lib/node_modules/vite-plus/dist/package.json'
    at async open (node:internal/fs/promises:640:25)

  code: 'ENOENT',
  syscall: 'open',
  path: '/Users/rokuosan/.local/share/mise/installs/viteplus/0.2.1/lib/node_modules/vite-plus/dist/package.json'
}

Node.js v24.17.0

Example without --debug:

$ vp staged
✔ Backed up original state in git stash (825fd1e)
✔ Hiding unstaged changes to partially staged files...
✔ Running tasks for staged files...
✔ Applying modifications from tasks...
✔ Restoring unstaged changes...
✔ Cleaning up temporary files...

This appears to be a Vite+ packaging/bundling issue rather than a lint-staged issue. The bundled staged entry contains lint-staged@16.4.0, but getVersion() resolves ../package.json relative to the bundled file, so it ends up reading vite-plus/dist/package.json.

Local-only workaround

As a local workaround, adding dist/package.json avoids the crash:

diff --git a/dist/package.json b/dist/package.json
new file mode 100644
index 0000000..653bf6d
--- /dev/null
+++ b/dist/package.json
@@ -0,0 +1,3 @@
+{
+  "version": "16.4.0"
+}

Steps to reproduce

1. Create a project with vite-plus@0.2.1
2. Configure staged in vite.config.ts
3. Stage at least one file
4. Run:

$ vp staged --debug

Hi @jong-kyung.

I noticed you're assigned here. I'd already put together a fix and opened #1925 before seeing the assignment, so apologies for the overlap.

If you're already working on this, feel free to ignore the PR — I'm happy to close it.
But if it's useful, please take a look; happy to adjust the approach based on your feedback.

In short, #1925 inlines the bundled lint-staged version at build time via a tsdown plugin,
so the debug path no longer reads ../package.json (which doesn't exist next to dist/staged/bin.js).
