feat(pack): add --exe flag and upgrade tsdown to 0.21.0-beta.2 (#646)

fengmk2 · web-flow · commit 0331ceffaec9 · 2026-02-27T14:08:29.000+08:00
## Summary - Upgrade tsdown from `0.20.3` to `0.21.0-beta.2` for experimental Node.js SEA support - Add `--exe` CLI option to `vp pack` for bundling as a standalone Node.js executable - Add RFC document for the full `vp pack` command - Add global snap tests for `--exe` success (Node.js 25.7.0) and error (Node.js < 25.5.0) cases - Fix size replacement regex in snap test utils to handle uppercase units (MB, GB) ## Test plan - [x] `pnpm -F vite-plus snap-test-local command-pack` — help output includes `--exe`, build/cache unchanged - [x] `pnpm -F vite-plus snap-test-global command-pack-exe` — successful exe build with Node.js 25.7.0 - [x] `pnpm -F vite-plus snap-test-global command-pack-exe-error` — clear error on Node.js < 25.5.0 🤖 Generated with [Claude Code](https://claude.com/claude-code)
