Paul Bakaus 4f7fdeca6b Build: ship launcher-only release zips by default
IMPECCABLE_BUNDLE_ENGINE=1 opts in to staging the engine binaries into the
dist skill copies. Bundling every target into every provider copy put
dist/universal.zip near 340 MB, past the 25 MB Cloudflare Pages file cap
that impeccable install downloads through.

Prepared with AI assistance (Claude Code).
