fix(wasm-worker): wire paramBindings, returnTypeMap, callAssignments through worker boundary (#1352)

These three ExtractorOutput fields were populated by the JS/TS extractor
but never included in SerializedExtractorOutput, causing them to be silently
dropped when results crossed the Worker thread boundary. The main thread
always received undefined for these fields regardless of what the worker
computed, breaking cross-file return-type propagation, param binding
resolution, and call-assignment tracking in the WASM engine.

Fixes #1348
