Subject: [PATCH] fix(core): wire @snowluma/proton vite plugin into the
 production build
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The proton plugin was only in `vitest.config.ts`, so tests and
typecheck passed but the bundled `dist/index.mjs` shipped with the
unsubstituted generic shells — every `protobuf_encode<T>()` /
`protobuf_decode<T>()` call hit the runtime fallback and threw:

  "protobuf_encode<T>() was not transformed by the
   @snowluma/proton Vite plugin. …"

at every msg-push, rkey/friend/group/profile warmup, etc. on the
Win/Linux releases.

Add `protobufVitePlugin()` to the shared `BaseConfigPlugin` so the
transform runs in both dev (`vite build --mode development`) and
prod (`vite build`). Sanity-check on a fresh `vite build` shows the
bundle now contains 481 distinct monomorphized codecs (704 encode +
511 decode call-site replacements), and the only remaining
"was not transformed" string is the dead runtime fallback that no
longer has a caller.
