feat(cli): replace vite-lib config with direct tsdown integration

[fengmk2]

TL;DR

Replaced the Rust-based Vite lib config generation with a Node.js implementation using the cac CLI library.

What changed?

• Removed the Rust code that was generating a temporary Vite lib config file
• Added a new lib-bin.ts file that implements the lib command functionality in Node.js
• Updated resolve-lib.ts to point to the new Node.js implementation
• Added cac as a dependency for command-line argument parsing
• Created a simple test CLI file to demonstrate cac usage

How to test?

1. Run vite lib command with various options
2. Verify that the command correctly processes arguments and passes them to tsdown
3. Check that the lib command correctly reads configuration from vite.config.ts

Why make this change?

This change simplifies the architecture by moving the lib command implementation from Rust to Node.js. Using cac for command-line parsing provides better flexibility and maintainability for the CLI interface. The Node.js implementation can directly interact with the tsdown API without needing to generate intermediate configuration files.

Note

Moves vite lib to a Node-based implementation and removes the interim Vite config generation.

• Adds src/lib-bin.ts using cac to implement vite lib, resolving vite.config.ts, forwarding flags, and calling build from @voidzero-dev/vite-plus-core/lib
• Removes Rust write_vite_lib_config path; simplifies cli.rs to call lib without generating vite-lib.config.js
• Updates resolve-lib.ts to run bundled lib-bin.js instead of tsdown’s run.js
• Refreshes help/flags and snapshots for vite lib; example outputs now show index.mjs
• Adds cac to workspace and lockfile

packages/cli/src/resolve-lib.ts:23

• The documentation comment still refers to "Tsdown binary path" and "resolves the Tsdown binary path using Node.js module resolution" and "executes Tsdown for running lib", but the implementation has changed to use a custom lib-bin.js file instead of Tsdown's binary. The comments should be updated to accurately reflect that this now resolves the custom lib command implementation rather than directly pointing to Tsdown.

 * Tsdown tool resolver for the vite-plus CLI.
 *
 * This module exports a function that resolves the Tsdown binary path
 * using Node.js module resolution. The resolved path is passed back
 * to the Rust core, which then executes Tsdown for running lib.
 *
 * Used for: `vite-plus lib` command
