描述

From #2705, when publishing shared worker messages, or replying to an individual message, we should enable values to be transferred.

I don't think a second "transfer list" API is a good fit for the shared worker API. Perhaps we could add a chaining API like .transferring(buffer1, messagePort2).publish({buffer1, messagePort2}) and .transferring(buffer1, messagePort2).reply({buffer1, messagePort2}).

Values can only be transferred once. This also means we can't add this to the .broadcast() method.

研究方向
Review the existing shared worker implementation in AVA, particularly the plugin.d.ts file (lines 35 and 41) and the related issue #2705. Investigate how the `.transferring()` chaining method could be added to both `publish()` and `reply()` methods. Ensure compatibility with the one time transfer constraint and avoid adding it to `.broadcast().
