fix: add missing path-posix workspace dependency after rolldown upgrade (#1375)

[Han5991]

Describe the bug

After running just init, cargo build (and any cargo command) fails because path-posix is missing from the root [workspace.dependencies] in Cargo.toml.

The upstream upgrade PR #1375 bumped rolldown to a version where rolldown_plugin_vite_import_glob added path-posix = { workspace = true } as a dependency. However, path-posix was not added to the root Cargo.toml, so Cargo cannot resolve it.

Error output:

error: failed to load manifest for workspace member `packages/cli/binding`
Caused by: failed to load manifest for dependency `rolldown_binding`
Caused by: failed to load manifest for dependency `rolldown_plugin_vite_import_glob`
Caused by: error inheriting `path-posix` from workspace root manifest's `workspace.dependencies.path-posix`
Caused by: `dependency.path-posix` was not found in `workspace.dependencies`

Reproduction

https://github.com/voidzero-dev/vite-plus

Steps to reproduce

1. Clone the repo: git clone https://github.com/voidzero-dev/vite-plus
2. Run just init (clones rolldown/vite upstreams and installs dependencies)
3. Run cargo check or any cargo command

Expected: Build succeeds
Actual: Error — path-posix not found in workspace dependencies
