- Transitions to using `tsx` for script execution
- Replaces `patch-package` with TypeScript implementation
- Implements argument parsing and help message with `yargs`
- Uses `execa` for some command execution
Test Plan: Run `pnpm pack-next`, `pnpm swc-build-wasm`, `pnpm unpack-next`, and `pnpm sweep` without errors.
### What?
Ports a few more useful scripts from nextpack, namely:
- `patch-next`
- `sweep`
- `build-native` (to clean up incremental artifacts on compiler panics)
- the macOS compression agent
